Momentum and Impulse

Momentum and Impulse

1. Momentum

   • p=mv
     • Momentum=mass x velocity
   • Law of conservation of momentum
     • Momentum cannot be created or destroyed
       • Momentum can be transferred
       • Forces can change momentum but are not creating it.
     • m1v1i + m2v2i = m1v1f + m2v2f

2. Impulse

   • Impulse Momentum Theorem
     • Force x Time=mass x change in velocity
       • F(tf-ti)=m(vf-vi)
   • Force cause changes in momentum
     • Bigger forces cause bigger changes in momentum
     • The longer a force is applied the bigger the change in momentum
