Energy & Collisions Flashcard

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 the stored energy in an object due to its position or state. For example, a book on a shelf has potential energy because it can fall.

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has. This is because it has the potential to fall a greater distance.

Front

What happens to kinetic energy when an object speeds up?

Back

When an object speeds up, its kinetic energy increases.

Front

What happens to kinetic energy when an object slows down?

Back

When an object slows down, its kinetic energy decreases.

Front

What is the relationship between energy and motion?

Back

Energy is required to create motion. The more energy applied, the greater the motion.

Front

What type of energy does a moving car have?

Back

A moving car has kinetic energy.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy.

Front

What is an example of kinetic energy in everyday life?

Back

An example of kinetic energy is a person running or a ball being thrown.

Front

What is an example of potential energy in everyday life?

Back

An example of potential energy is water stored in a dam.
