Newton's third law
whenever one object exerts a force on a second object the second object exerts an equal and opposite force on the first
product of mass the of an object and its velocity
The product of the force and the distance moved by the force
energy of motion quantified by the relationship
Kinetic energy =
conservation of energy
energy cannot be created or destroyed it may be transformed from one form into another but the total amount of energy never changes.
work energy theorem
the work done on an object equals the change in kinetic energy of the other object.
