Momentum and Impulse
- 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
- 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
- Vector Quantities
