Impulse and Momentum Theorem 

Impulse is known as the change in momentum of any object: j = Δp 

Momentum is a product of the mass & the velocity of an object, and is a vector quantity: 

It can be shown as p = mv 

This in daily routine life we usually can not notice an object''s mass change because of its velocity changes. 

The change in momentum is shown by equation: 

Δp = mΔv 

Impulse occurs dure to force is applied to an object over period of time: which is shown as equation j = F Δ t 

Thus shown  j =  Δ p,  F Δ t = m Δ v, F = m Δ v/ Δ t 

Newton''s Second Law of Motion is force,  the rate of change of momentum: 

F = Δp/t 

Example Momentum Problem 

Calculate momentum of an object with m=2.00 kg & v-40.0 m/s? 

Answer to Example Momentum Problem 

p = mv =  (2.00)(40.0) = 80.0 kg*m/s
