Momentum, Collision and Impulse
-
Collision
Definition :
An isolated event in which two or more bodies (the colliding bodies) exert relatively strong forces on each other for a relatively short time.
-
Elastic Collision
- One in which the total kinetic energy(as well as total momentum) of the system is the same before and after the collision
- The coefficient of restitution, e =1
- The total momentum is conserved
∑p initial = ∑p final
- The total kinetic energy is conserved
∑K initial = ∑K final
Inelastic Collision
- One in which the total kinetic energy of the system is not the same before and after the collision
- the coefficient of restitution, 0 <= e <1
- the total momentum is conserved
∑p initial = ∑p final
- the total kinetic energy is not conserved.
But the total energy is conserved
∑E initial = ∑E finalor∑K initial = ∑K final + losses energy
Momentum
-
Definition
-
If the object is not moving then there is 0 momentum, since v=0.

Impulse is defined as the product of a force,F and the time,t OR the change of momentum
