Newton's first law of motion states:
For every action there is an equal and opposite reaction.
The acceleration of an object is directly proportional to the force exerted on the object and inversely proportional to the mass of the object.
An object at rest will stay at rest and an object in motion will stay in motion at a constant velocity unless acted upon by a net force.
F=ma

Which definition matches an elastic collision?
Both momentum and KE are conserved.
Momentum is conserved, but KE is transferred into a different form of energy.
Momentum is not conserved, but KE is conserved.
Momentum is not conserved because some of the KE is transferred into deformation of the two objects.
