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
