This equation computes the impulse due to change in speed (so change in velocity neglecting any change in direction)

INPUTS

  • m - mass
  • `v_i` -  initial velocity
  • `v_f` - final velocity

NOTES

Impulse (J) is the product of force and time.  Impulse is also the change in momentum, where momentum is mass x velocity.  

`J = m*deltat = F_"average" * delta t`
