ΣF = Δp/Δt **Net force equals the change in momentum per unit time Rearranging this equation Δp = ΣFΔt
Impulse (J)
The change in momentum is called the impulse of the force (Impulse- momentum theorem)
Vector quantity
Units: kg * m/s
J = Δp = FavgΔt
p = Momentum
J = Impulse
Favg = Average force
Δt = Elapsed time
The greater the net force, or the longer the interval of time it is applied, the more the object’s momentum changes the same as saying the impulse increases
