Energy Types and Conservation Concepts

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work. It is energy based on an object's position or condition.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

At which point of a roller coaster is potential energy the greatest?

Back

Potential energy is greatest at the highest point of the 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 stretched rubber band have?

Back

A stretched rubber band has potential energy.

Front

Where is kinetic energy the greatest on a roller coaster?

Back

Kinetic energy is greatest at the lowest point of the roller coaster.

Front

What is the relationship between potential and kinetic energy in a closed system?

Back

In a closed system, potential energy can be converted to kinetic energy and vice versa, but the total energy remains constant.

Front

Give an example of potential energy in everyday life.

Back

An example of potential energy is a book on a shelf. It has potential energy due to its height.

Front

Give an example of kinetic energy in everyday life.

Back

An example of kinetic energy is a moving car.

Front

What is gravitational potential energy?

Back

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