Momentum and impulse and work energy and power all definitions

Linear momentum

The product of the mass and velocity of the object

Newton’s second law in terms of momentum

The net force on an object is equal to the rate of change of momentum

The law of conservation of linear momentum

The total linear momentum of an isolated system remains constant

An elastic collision

A collision in which both momentum and kinetic energy is conserved

Inelastic collision

A collision in which only momentum is conserved

Impulse

The product of the net force and the contact time

Work done on a object by a force

The product of the displacement and the component of the force parallel to the displacement

Gravitational potential energy

The energy an object possesses due to its position relative to a reference point

Kinetic energy

The energy an object has as a result of the objects motion

Mechanical energy

The sum of gravitational potential and kinetic energy at a point

The law of conservation of energy

The total energy in a system cannot be created or destroyed, only transformed from one form to another

Principle of conservation of mechanical energy

In the absence of air resistance or any external forces, the mechanical energy of an object is constant

Work energy theorem

The work done by a net force on an object is equal to the change in the kinetic energy of the object

Power

The rate at which work is done
