Potential and Kinetic Energy

Front

What determines the amount of kinetic energy in an object?

Back

The amount of kinetic energy in an object is determined by its speed and mass.

Front

What is the energy stored in an object called?

Back

Potential energy.

Front

What factors determine the amount of potential energy in an object?

Back

Distance (height) and mass.

Front

When is elastic potential energy at its greatest?

Back

When a rubber band is stretched all the way.

Front

What type of energy does a basketball have when it sits on the rim before falling?

Back

Potential energy.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is speed.

Front

What is the formula for potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does height affect potential energy?

Back

Potential energy increases with height; 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; if speed doubles, kinetic energy increases by a factor of four.

Front

What type of energy is associated with the position of an object?

Back

Potential energy.
