Why?
Because it has a larger mass
Than the other

8. Which has more kinetic energy?
If these are the same mass… ✔
5 m/s
7 m/s
Why?
Because it has a greater speed

9. Roller Coaster Animation

10. Where does the pendulum have the
most potential energy?
Where does it have the most kinetic energy?
A and C B

11. What is the Law of Conservation of Energy?
Energy cannot be created or destroyed
It can only only be transformed (changed) from one form to another.
In the animation, kinetic energy is constantly changing to potential and potential is changing to kinetic but the total amount of energy in the circle always stays the same.
