Impulse-Momentum Theorem

 

Impulse-Momentum Theorem formula

  • This equation shows that applying a force to an object for a certain duration results in a change in its velocity, and consequently, a change in momentum.

FΔt=mΔv     (Impulse-Momentum)

F=mΔvΔt

m=FΔtΔv

Δv=FΔtm

Δt=mΔvF

Symbol English Metric
F = Force lbf  N 
m = Mass lbm kg
Δv = Velocity Change ft/sec   m/s
Δt = Time Change sec s

The impulse experienced by an object is related to the change in its momentum when a force is applied.  The impulse-momentum theorem states that the impulse, abbreviated as J, experienced by an object is equal to the change in its momentum, abbreviated as Δp.  This relationship can be expressed as  If a force ( F) is applied to an object for a certain duration ( Δt), the impulse experienced by the object is given by
