Mechanical Energy Test Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or height. For example, a bicycle at the top of a hill has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. For example, a bicycle moving down a hill has kinetic energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object.

Front

What happens to potential energy as an object moves down a hill?

Back

As an object moves down a hill, its potential energy decreases while its kinetic energy increases.

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is an example of kinetic energy in everyday life?

Back

A flowing river is an example of kinetic energy because the water is in motion.

Front

What is an example of potential energy in everyday life?

Back

A book on a shelf has potential energy because it can fall due to gravity.

Front

What is transferred when two objects collide?

Back

Energy is transferred when two objects collide.

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed of an object.
