What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, which can be converted into kinetic energy when the object is in motion.

Front

When does an object have the most potential energy when placed on a ramp?

Back

An object has the most potential energy at the highest point of the ramp.

Front

Give an example of potential energy.

Back

A rock sitting on top of a high ledge is an example of potential energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is the definition of energy?

Back

Energy is the ability to do work.

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 is involved when a person pushes a heavy box?

Back

The type of energy involved is mechanical energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

How is energy conserved in a closed system?

Back

In a closed system, energy cannot be created or destroyed, only transformed from one form to another.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.
