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

Question

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

(1 point)
Responses

kinetic energy

motion energy

electrical energy

potential energy

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

potential energy stays the same as it falls

kinetic energy converts to potential energy as it falls

potential energy converts to kinetic energy as it falls

kinetic energy stays the same 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.

Both speed and kinetic energy are at their lowest values.

Both speed and kinetic energy are at their greatest values.

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

Answer 1

a. When the ball is held at the top of the table (before being dropped), it has potential energy.

b. As the ball is falling, its potential energy converts to kinetic energy.

c. Just before the ball hits the ground, its speed is at its highest value, while its kinetic energy is also at its highest value.
