6th Grade: Kinetic energy and potential energy

2. Kinetic Energy (Page 15) Has anyone ever been on an airplane?
What are G-forces?
Gravitational forces (Gravity is 9.8 meters per second per second)
A pilot flying at 3-g’s is accelerating at three times the rate of gravity

3. Math Toolbox (Page 16)
Kinetic Energy = x Mass x Speed²

4. Potential Energy (Page 17)
If someone has great potential, have they given the task everything they’ve got?
How is a person’s potential like the potential energy of an object?

5. Stored-Up Energy (Page 17 – Figure 2)
When a rubber band is stretched then released, what kind of energy will it have?

6. Gravitational Potential Energy (Page 18)
What pulls on objects with Gravitational Potential Energy?
What factors affect Potential Energy?
How is Gravitational Potential Energy measured?
GPE = Weight x Height
How would a cyclist’s GPE compare if the cyclist were on a taller hill?
A shorter hill?
A small child and a teenager are at the top of a hill on skateboards. What could the child do to increase their GPE?

7. Gravitational Potential Energy (Page 18 – Figure 3)
What makes it possible for the cyclist to have Gravitational Potential Energy?

8. Elastic Potential Energy (Page 19 – Figure 4)
Rank the amount of EPE of the trampoline from greatest to least using words most, medium, and least.

9. Reading Check (Page 19)
Explain your rankings of the trampoline’s potential energy.

10. Potential vs Kinetic Energy
What are some analogies that show the relationship of potential energy changing to kinetic energy?
Potential Energy is food on a plate and Kinetic Energy is eating the food.
Potential Energy is listening to instructions and Kinetic Energy is performing the task.
Can an object have potential energy without kinetic energy?
Can an object have kinetic energy without potential energy?
