The rate of change of momentum of a body is proportional to the resultant force acting on the body and is in the same direction. The change in momentum of a particle during a time interval equals the impulse of the net force that acts on the particle during that interval.
Using our de nition of impulse from Eq.4, we arrive at the impulse-momentum theorem: ~J = ~p 2 ~p 1 (impulse-momentum theorem) (5) The change in momentum of a particle equals the net force multiplied by the time interval over which the net force is applied. If the P~ P F is not constant, we can integrate both sides of Newton’s second law
Momentum and impulseThe momentum of a particle at a given time is defined as the product of its mass with its velocity and is measured in N. ⃗p = m ⃗v. Impulse is defined as the definite integral of force with respect to time and is equal to the change in momentum. t2 t2 t2. ⃗J = ∫ ⃗F dt d ⃗v = ∫ m = ∫ m d ⃗v = Δ ⃗p.
