The product of the mass of an object and it's velocity.
The product of the force acting on an object and the time during which it acts.
|Relationship of impulse and momentum||
Impulse is equal to the change in momentum of the object that the impulse acts upon.
Ft=change in mv
|Law of conservation of momentum||
In the absence of an external force, the momentum of a system remains unchanged. Hence, the momentum before an event involving only external forces is equal to the momentum after the event:
mv(before event) = mv(after event)
A collision in which colliding objects rebound without lasting deformation or the generation of heat.
A collision in which the colliding objects become distorted, generate heat, and possibly stick together.
