Question
Amy is at basketball practice. She is about to shoot a free throw.When Amy releases the ball, A. the ball will have neither kinetic energy nor potential energy. B. the ball will not have kinetic energy but will have potential energy. C. the ball will have kinetic energy and potential energy. D. the ball will have kinetic energy but will not have potential energy.
Solution
The correct answer is C. the ball will have kinetic energy and potential energy. Here's why:
-
Potential Energy: When Amy holds the ball at a certain height, the ball has potential energy. This is because potential energy is the energy that an object has due to its position relative to other objects. In this case, the ball has potential energy due to its height above the ground.
-
Kinetic Energy: When Amy releases the ball, it starts moving. As soon as the ball is in motion, it has kinetic energy. This is because kinetic energy is the energy of motion. The faster an object moves, the more kinetic energy it has.
So, when Amy releases the ball, it has both kinetic energy (because it's moving) and potential energy (because of its height above the ground).
