Understanding Gravitational Potential Energy: Calculations and Examples

What happens to the energy stored in an object when it is lifted vertically?

• It decreases.

• It is converted to kinetic energy.

• It remains the same.

• It increases.

Which of the following is NOT a component of the gravitational potential energy formula?

• Velocity of the object

• Gravitational field strength

• Mass of the object

• Change in height

If a book is lifted to a higher shelf, what happens to its gravitational potential energy?

• It decreases.

• It remains constant.

• It becomes zero.

• It increases.

When a book is lowered from a height, what is the sign of the change in gravitational potential energy?

• Undefined

• Zero

• Negative

• Positive

In the example of the football, what is the change in gravitational potential energy when it reaches the top of the kick?
