Potential and Kinetic Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What factors affect kinetic energy?

Back

Kinetic energy depends on two factors: the mass of the object and the speed at which it is moving.

Front

Where is potential energy highest on a roller coaster?

Back

Potential energy is highest at the top of a big hill on a roller coaster.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

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

If two vehicles are moving at the same speed, which has greater kinetic energy?

Back

The vehicle with greater mass has greater kinetic energy.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is speed.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has due to the force of gravity acting on it.
