Question

Which of the following has potential but not kinetic energy?

A.) A roller coaster zooming down a hill

B.) A child riding their bike

C.)A bird flying from a tree

D.) A ball sitting on a shelf

Answer 1

Potential energy is turned into kinetic energy. Potential energy itself is determined by the position and forces on an object. Kinetic energy is based on the velocity of the object. So when an object sitting still is moved, the potential energy is quickly converted into kinetic energy because it is moving with a velocity.

A ball sitting still on a shelf will have a huge amount of potential energy because we would consider the reference point to be the ground. There is a change in height from the top of the shelf and the ground, but there is no velocity

Answer 2

D.)

Step-by-step explanation:

Potential energy is when a object is not in motion and the ball is sitting on a shelf not being thrown around or rolling. kinetic energy is when a obeject is in motion and moving.
