Potential and Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is Potential Energy?

Back

Potential energy is stored energy that an object has due to its position or condition. For example, a rock at the top of a cliff has potential energy.

Front

How does the speed of an object affect its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What happens to potential energy as a rock falls from a cliff?

Back

As the rock falls, its potential energy decreases while its kinetic energy increases.

Front

Where is the maximum kinetic energy on a roller coaster?

Back

The maximum kinetic energy is at the bottom of a big hill.

Front

What type of energy does a baseball have when held by a pitcher?

Back

A baseball held by a pitcher has potential energy.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy. For example, when an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is an example of potential energy?

Back

A stretched rubber band has potential energy because it can do work when released.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy because it is in motion.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)².
