Question

Consider the concepts of kinetic energy (KE) and gravitational potential energy (GPE) as you complete these questions. A ball is held 1.4 meters above the floor. Use the terms KE of GPE as your answers.

A.When the ball is held motionless above the floor, the ball possesses only? Gravitational Potential Energy.
B.If the ball is dropped, its? GPE decreases as it falls.
C.If the ball is dropped, its? KE increases as it falls.
D.In fact, in the absence of air resistance, the amount of? GPE when the ball is held motionless above the floor equals the amount of? KE at impact with the floor.

Answer 1

When the ball is held motionless above the floor, it possesses Gravitational Potential Energy (GPE). If the ball is dropped, its GPE decreases as it falls, while its Kinetic Energy (KE) increases. In the absence of air resistance, the GPE of the ball held motionless above the floor is equal to the KE at impact with the floor.

Step-by-step explanation:

A. When the ball is held motionless above the floor, the ball possesses only Gravitational Potential Energy (GPE).

B. If the ball is dropped, its GPE decreases as it falls.

C. If the ball is dropped, its Kinetic Energy (KE) increases as it falls.

D. In fact, in the absence of air resistance, the amount of GPE when the ball is held motionless above the floor equals the amount of KE at impact with the floor.
