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
