A ball is held at the edge of a table top. The person holding the ball drops it, and the ball is allowed to fall toward Earth. Answer the following questions about the ball.

a. When the ball is held at the edge of the top of the table (before being dropped), what type of energy does the ball have?

Question 2
b. As the ball is falling, what is happening to its energy?(1 point)
Responses

kinetic energy stays the same as it falls
kinetic energy stays the same as it falls

potential energy stays the same as it falls
potential energy stays the same as it falls

kinetic energy converts to potential energy as it falls
kinetic energy converts to potential energy as it falls

potential energy converts to kinetic energy as it falls
potential energy converts to kinetic energy as it falls
Question 3
c. Just before the ball hits the ground, how are its speed and kinetic energy related?(1 point)
Responses

Speed is at its lowest value, which kinetic energy is at its highest value.
Speed is at its lowest value, which kinetic energy is at its highest value.

Speed is at its highest value, while kinetic energy is at its lowest value.
Speed is at its highest value, while kinetic energy is at its lowest value.

Both speed and kinetic energy are at their lowest values.
Both speed and kinetic energy are at their lowest values.

Both speed and kinetic energy are at their greatest values.
Both speed and kinetic energy are at their greatest values.
