Front

What happens to the force needed to move an object when it is moved using an inclined plane?

Back

The force needed to move the object decreases.

Front

What is an example of radiant energy?

Potential energy.

Front

What type of energy is associated with an object's motion?

Back

Kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity).

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is gravitational potential energy dependent on?

Back

Mass, height, and the acceleration due to gravity.
