Use the impulse formula: (J = FDelta t)
If force changes with time, use: (J = int F,dt)
Use the momentum form: (J = Delta p = m(v_f – v_i))
Identify the mass, initial velocity, and final velocity
Calculate the change in velocity: (v_f – v_i)
Multiply the mass by the change in velocity
If force and time are given, multiply force by time
If force varies, find the area under the force-time graph
Express the result in newton-seconds or kilogram-meters per second
