Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

How does kinetic energy change as an object moves in a gravitational field?

Back

Kinetic energy increases as an object falls and decreases as it rises in a gravitational field.

Front

What happens to potential energy when an object is lifted to a higher position?

Back

The potential energy of the object increases as it is lifted to a higher position.

Front

In the context of a swing, where is the kinetic energy the greatest?

Back

The kinetic energy is greatest at the lowest point of the swing.

Front

In the context of a swing, where is the potential energy the greatest?

Back

The potential energy is greatest at the highest points of the swing.

Front

What type of energy does a child have at the top of a swing's arc?

Back

At the top of a swing's arc, the child has maximum potential energy and minimum kinetic energy.

Front

What type of energy does a child have at the bottom of a swing's arc?

Back

At the bottom of a swing's arc, the child has maximum kinetic energy and minimum potential energy.

Front

What is an example of potential energy in nature?

Back

An acorn hanging from an oak tree is an example of potential energy.

Front

What is the relationship between kinetic energy and potential energy in a rolling ball?

Back

As a ball rolls uphill, some of its kinetic energy is converted into potential energy.
