Front

Energy can be _____________ or changed from one type to another.

Back

transferred

Front

Choose the BEST answer that is an example of an energy transformation from potential energy to kinetic energy.

Back

a swing swaying back and forth

Front

Gravitational potential energy depends on the ________ and ________ of the object.

Back

Height and mass

Front

When a football player kicks a ball, he transfers energy to the ball. What happens as a result?

Back

the ball gains kinetic energy

Front

Gravitational potential energy depends on the ________ and ________ of the object.

Back

Height and mass

Front

What is the definition of kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

What is the formula for gravitational potential energy?

Back

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

Front

What is the law of conservation of energy?

Back

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

Front

Give an example of energy transformation in a roller coaster.

Back

As the coaster climbs, potential energy increases; as it descends, potential energy converts to kinetic energy.
