Module 5 Review (8th)

Front

What types of energy does a blimp circling above a sporting event have?

Back

Kinetic energy and gravitational potential energy.

Front

According to the law of conservation of energy, what happens to the total amount of energy in the universe?

Back

It remains constant.

Front

When a rubber ball is dropped and bounces back up, where is the ball's potential energy at its maximum?

Back

At point A (the highest point before it drops).

Front

According to the Law of Conservation of Energy, energy cannot be what?

Back

Created or destroyed.

Front

What happens to the kinetic energy when the mass of a moving object increases?

Back

The kinetic energy increases by the same factor as the mass increase.

Front

Define kinetic energy.

Back

The energy an object possesses due to its motion.

Front

Define gravitational potential energy.

Back

The energy an object possesses due to its position in a gravitational field.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for gravitational potential energy?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
