Energy Transformation for Downhill Skiing

Downhill skiing is a classic illustration of the relationship between work and energy. The skier begins at an elevated position, thus possessing a large quantity of potential energy (i.e., energy of vertical position). If starting from rest, the mechanical energy of the skier is entirely in the form of potential energy. As the skier begins the descent down the hill, potential energy is lost and kinetic energy (i.e., energy of motion) is gained. As the skier loses height (and thus loses potential energy), she gains speed (and thus gains kinetic energy). Once the skier reaches the bottom of the hill, her height reaches a value of 0 meters, indicating a total depletion of her potential energy. At this point, her speed and kinetic energy have reached a maximum. This energy state is maintained until the skier meets a section of unpacked snow and skids to a stop under the force of friction. The friction force, sometimes known as a dissipative force, does work upon the skier in order to decrease her total mechanical energy. Thus, as the force of friction acts over an increasing distance, the quantity of work increases and the mechanical energy of the skier is gradually dissipated. Ultimately, the skier runs out of energy and comes to a rest position. Work done by an external force (friction) has served to change the total mechanical energy of the skier.

This intricate relationship between work and mechanical energy is depicted in the animation below.

Along the inclined section of the run, the total mechanical energy of the skier is conserved provided that:

• there is a negligible amount of dissipative forces (such as air resistance and surface friction), and
• the skier does not utilize her poles to do work and thus contribute to her total amount of mechanical energy

Provided that these two requirements are met, there would be no external forces doing work upon the skier during the descent down the hill. The force of gravity and the normal forces would be the only active forces. While the normal force is an external force, it does not do work upon the skier since it acts at a right angle to the skier's displacement. In such situations where the angle between force and displacement is 90-degrees, the force does not do work upon the skier. Consequently, the force of gravity is the only force doing work on the skier and therefore the total mechanical energy of the skier is conserved. Potential energy is transformed into kinetic energy; and the potential energy lost equals the kinetic energy which is gained. Overall, the sum of the kinetic and potential energy remains a constant value.

The numerical values and accompanying bar chart in the animation above depicts these principles. During the descent down the hill, the height of the total mechanical energy (TME) bar remains a constant quantity, indicating the conservation of total mechanical energy. Furthermore, as the height of the potential energy (PE) bar decreases, the height of the kinetic energy (KE) bar increases.

Near the end of the run, the skier encounters the force of friction. This force acts in the direction opposite the displacement of the skier. The angle between the force and the displacement is 180 degrees. Using the equation for work (F*d*cosine 180 degrees), the amount of work can be calculated. The value calculated from the above equation is a negative number, indicating that the work done serves to remove energy from the object. This is why friction is sometimes referred to as a dissipative force . The amount of work which is done is equal to the loss of mechanical energy. The bar chart in the animation above depicts a work (W) bar with a negative height . As this bar becomes more negative, the height of the total mechanical energy (TME) bar becomes smaller. By the end of the animation, the work bar has reached a height of -8 units and the total mechanical energy bar has change its height from +8 units to 0 units. Thus, the change in height of the total mechanical energy bar (-8 units) equals the height of the work bar (-8 units).

Teaching Resources

Forms of Energy Activities for Kids (and free anchor charts)

Take It Slow

Teaching students about forms of energy can sometimes feel like an overwhelming task! One trick that I have found that helps, is breaking it up into chunks. Don’t jump in head first, by telling students all of the different forms, then teaching them all at once. You will overwhelm yourself and your students. Take it slow! Another tip- find lessons and resources you enjoy doing. Don’t do elaborate science experiments if that’s not your jam! It doesn’t have to be fancy to be fun! I have included some of my favorite forms of energy activities for kids to help make your planning easier.

Make a plan

First things first. Make a plan! Decide what forms of energy your students need to know. Since I teach the TEKS, my students need to know about sound , light , and heat . (this is second grade). I like to first start out by teaching what energy is, then each week I focus on a new form of energy. Spending a week on each energy is more than enough and it helps easily break up each form into a doable schedule. 

What is Energy?

Energy is what we need to get work done! Energy is coffee… no not really, but kind of- right. Sadly we aren’t teaching that kind of energy, but I would like to know how I can get more of that! I tell my students that energy is how we do things and that it is something we need in order to work. Here is a list of resources you can check out to help you teach the first concept.

Forms of Energy Activities and Resources:

Here is a list of forms of energy activities and resources that I use in my class. A lot of the resources from this post are from my Forms of Energy worksheet Pack .

FREE Forms of energy anchor charts

Grab some free anchor chart templates to help you teach your class about sound, light, and heat energy!

Forms of Energy Websites

• Kids Korner is a simple website that explores the different forms and explains what energy is for kids. The website also has lots of ideas about forms of energy activities and resources to use.
• Brainpop Jr. is my favorite resource if you have access. My kids love watching the video and then completing the quizzes.
•   E School Today is another great science website that breaks down the different forms of energy for kids.
• Dr. Binocs video on energy is great he has a view that go over each topic. This is a good one to start with.

Books to Teach About Forms of Energy

Oh, my love for amazon runs so deep! Books are such a great way to incorporate language arts into science. Here is a list of some of my favorites!

• The Shocking Truth About Energy is a great book with fun illustrations that show how energy can travel from different places and take on different forms. The Author is Loreen Leedy. She has some other great books too!
• Energy Makes Things Happen by Kimberly Bradley.  This is an old one, but I finally decided to take it out of my library and read it. I am pretty sure that this was a hand me down given to me by a retired teacher, but it is worth the read and is a relatively inexpensive and easy to find book!
• Light is All Around Us by Wendy Pfeffer is a good book that talks about the different forms of light. (I read this book then make an anchor chart to go with it!)
• Sound is All Around Us is by Wendy Pfeffer too. It goes great with the light book because the illustrations and style is the same. Once I have read both I leave these books in our science center for my students to read.
• The Energy that Warms Us is my go-to book to kick off our unit in heat. I have found that there are not as many books about heat as there are light and sound. This book is by Jennifer Boothroyd.

Forms of Energy Anchor Charts Ideas

Here are a few anchor charts I made to go along with teaching this topic. I created these one at a time, and once I introduced the new form of energy I had students share their ideas on sticky notes.

Using sticky notes helps me recycle the charts so that I can use them next year! I put them on binder rings and hang them up on my anchor chart wall.

Science Experiments

To help give students a hands-on approach to learning these concepts, I use hands-on activities and experiments to get them excited about learning.

Sometimes it’s hard to squeeze it all in. So, I will put the extra worksheets from my forms of energy unit into my science center or give the activities as a homework assignment.

Conceptual Questions

7.1: work: the scientific definition.

1. Give an example of something we think of as work in everyday circumstances that is not work in the scientific sense. Is energy transferred or changed in form in your example? If so, explain how this is accomplished without doing work.

2. Give an example of a situation in which there is a force and a displacement, but the force does no work. Explain why it does no work.

3. Describe a situation in which a force is exerted for a long time but does no work. Explain.

7.2: Kinetic Energy and the Work-Energy Theorem

4. The person in Figure does work on the lawn mower. Under what conditions would the mower gain energy? Under what conditions would it lose energy?

5. Work done on a system puts energy into it. Work done by a system removes energy from it. Give an example for each statement.

6. When solving for speed in Example, we kept only the positive root. Why?

7.3: Gravitational Potential Energy

7. In Example, we calculated the final speed of a roller coaster that descended 20 m in height and had an initial speed of 5 m/s downhill. Suppose the roller coaster had had an initial speed of 5 m/s uphill instead, and it coasted uphill, stopped, and then rolled back down to a final point 20 m below the start. We would find in that case that its final speed is the same as its initial speed. Explain in terms of conservation of energy.

8. Does the work you do on a book when you lift it onto a shelf depend on the path taken? On the time taken? On the height of the shelf? On the mass of the book?

7.4: Conservative Forces and Potential Energy

9. What is a conservative force?

10. The force exerted by a diving board is conservative, provided the internal friction is negligible. Assuming friction is negligible, describe changes in the potential energy of a diving board as a swimmer dives from it, starting just before the swimmer steps on the board until just after his feet leave it.

11. Define mechanical energy. What is the relationship of mechanical energy to nonconservative forces? What happens to mechanical energy if only conservative forces act?

12. What is the relationship of potential energy to conservative force?

7.6: Conservation of Energy

13. Consider the following scenario. A car for which friction is not negligible accelerates from rest down a hill, running out of gasoline after a short distance. The driver lets the car coast farther down the hill, then up and over a small crest. He then coasts down that hill into a gas station, where he brakes to a stop and fills the tank with gasoline. Identify the forms of energy the car has, and how they are changed and transferred in this series of events. (See Figure.)

A car experiencing non-negligible friction coasts down a hill, over a small crest, then downhill again, and comes to a stop at a gas station.

14. Describe the energy transfers and transformations for a javelin, starting from the point at which an athlete picks up the javelin and ending when the javelin is stuck into the ground after being thrown.

15. Do devices with efficiencies of less than one violate the law of conservation of energy? Explain.

Solution (a) \(\displaystyle 0.500 m/s^2\) (b) \(\displaystyle 62.5 N\) (c) Assuming the acceleration of the swimmer decreases linearly with time over the 5.00 s interval, the frictional force must therefore be increasing linearly with time, since \(\displaystyle f=F−ma\). If the acceleration decreases linearly with time, the velocity will contain a term dependent on time squared (\(\displaystyle t^2\)). Therefore, the water resistance will not depend linearly on the velocity.

A toy gun uses a spring with a force constant of 300 N/m to propel a 10.0-g steel ball. If the spring is compressed 7.00 cm and friction is negligible:

(a) How much force is needed to compress the spring?

(b) To what maximum height can the ball be shot?

(c) At what angles above the horizontal may a child aim to hit a target 3.00 m away at the same height as the gun?

(d) What is the gun’s maximum range on level ground?

90. Integrated Concepts

(a) What force must be supplied by an elevator cable to produce an acceleration of \(\displaystyle 0.800 m/s^2\) against a 200-N frictional force, if the mass of the loaded elevator is 1500 kg?

(b) How much work is done by the cable in lifting the elevator 20.0 m?

(c) What is the final speed of the elevator if it starts from rest?

(d) How much work went into thermal energy?

Solution (a) \(\displaystyle 16.1×10^3N\) (b) \(\displaystyle 3.22×10^5J\) (c) \(\displaystyle 5.66 m/s\) (d) 4.00 kJ

91. Unreasonable Results

A car advertisement claims that its 900-kg car accelerated from rest to 30.0 m/s and drove 100 km, gaining 3.00 km in altitude, on 1.0 gal of gasoline. The average force of friction including air resistance was 700 N. Assume all values are known to three significant figures.

(a) Calculate the car’s efficiency.

(b) What is unreasonable about the result?

(c) Which premise is unreasonable, or which premises are inconsistent?

92. Unreasonable Results

Body fat is metabolized, supplying 9.30 kcal/g, when dietary intake is less than needed to fuel metabolism. The manufacturers of an exercise bicycle claim that you can lose 0.500 kg of fat per day by vigorously exercising for 2.00 h per day on their machine.

(a) How many kcal are supplied by the metabolization of 0.500 kg of fat?

(b) Calculate the kcal/min that you would have to utilize to metabolize fat at the rate of 0.500 kg in 2.00 h.

(c) What is unreasonable about the results?

(d) Which premise is unreasonable, or which premises are inconsistent?

Solution (a) \(\displaystyle 4.65×10^3kcal\) (b) 38.8 kcal/min (c) This power output is higher than the highest value on [link], which is about 35 kcal/min (corresponding to 2415 watts) for sprinting. (d) It would be impossible to maintain this power output for 2 hours (imagine sprinting for 2 hours!).

93. Construct Your Own Problem

Consider a person climbing and descending stairs. Construct a problem in which you calculate the long-term rate at which stairs can be climbed considering the mass of the person, his ability to generate power with his legs, and the height of a single stair step. Also consider why the same person can descend stairs at a faster rate for a nearly unlimited time in spite of the fact that very similar forces are exerted going down as going up. (This points to a fundamentally different process for descending versus climbing stairs.)

94. Construct Your Own Problem

Consider humans generating electricity by pedaling a device similar to a stationary bicycle. Construct a problem in which you determine the number of people it would take to replace a large electrical generation facility. Among the things to consider are the power output that is reasonable using the legs, rest time, and the need for electricity 24 hours per day. Discuss the practical implications of your results.

95. Integrated Concepts

A 105-kg basketball player crouches down 0.400 m while waiting to jump. After exerting a force on the floor through this 0.400 m, his feet leave the floor and his center of gravity rises 0.950 m above its normal standing erect position.

(a) Using energy considerations, calculate his velocity when he leaves the floor.

(b) What average force did he exert on the floor? (Do not neglect the force to support his weight as well as that to accelerate him.)

(c) What was his power output during the acceleration phase?

Solution (a) 4.32 m/s (b) \(\displaystyle 3.47×10^3N\) (c) 8.93 kW
