Mechanical Energy

Power

is a measure of the rate at which work is done or energy is transferred.

Impulse

What is the force applied to an object over a given time interval?

positive

What type of collisions DO NOT conserve kinetic energy?

rate of transfer of energy

Power is the

Work-Kinetic Energy Theorem

What theorem states that the change in kinetic energy of an object is equal to the work done on the object?

Momentum
