Physics definitions - impulse and momentum

Linear momentum

The product of the mass and velocity of the object.

newtons 2nd law (in terms of momentum)

The net force acting 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.

elastic collision

A collision in which both momentum and kinetic energy are conserved.

inelastic collision

A collision in which only momentum is conserved.

Impulse

The product of the net force and the contact time.

work

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

energy

The ability to do work.

Gravitational potential energy

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

Kinetic energy

the energy an object has because of the objects motion.

The principle of the conversation of energy

The total energy is a system cannot be created nor destroyed; only transformed from one form to another.

work-energy theorem

The work done by the resultant (net) force on an object is equal to the change in kinetic energy of that object.
