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? (1 point) Responses motion energy motion energy potential energy potential energy kinetic energy kinetic energy electrical energy electrical 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 potential energy stays the same as it falls kinetic energy converted to potential energy as it falls kinetic energy converted to potential energy as it falls potential energy converts to kinetic energy as it falls potential energy converts to kinetic energy as it falls kinetic energy stays the same 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 Both speed and kinetic energy are at their greatest values. Both speed and kinetic energy are at their greatest values. 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.

Answer 1

Here are the answers to your questions:

Question 1: 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?

• Response: potential energy

Question 2: b. As the ball is falling, what is happening to its energy?

• Response: 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?

• Response: Both speed and kinetic energy are at their greatest values.
