Potential Energy, Kinetic Energy, Mass, and Speed

Front

What is energy?

Back

Energy is the ability to do work.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

How can you increase the potential energy of an object?

Back

You can increase the potential energy of an object by raising it higher.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What factors affect potential energy?

Back

Potential energy is affected by the height of the object and its mass.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with an increase in mass, assuming speed remains constant.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

Front

What is gravitational potential energy?

Back

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