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
