Momentum

Momentum and Impulse

Momentum is mass in motion, and any moving object will have momentum.
Momentum = mass x velocity
p = mv

(The letter p represents momentum; ρ (Rho) represents density)

Meanwhile, an object’s change in momentum is its impulse. 
Impulse = Change in momentum
Ft = mv – mu 

Conservation of Momentum

The law of momentum conservation ca be stated as follows. For a collision between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Total momentum before = total momentum after
