Linear Momentum
by Mary Lager
1. Impulse Momentum Theorem
1.1. change in p=sum of the F*change of t
1.2. the change in momentum equals the impulse
1.3. Impusle
1.3.1. N*s
1.3.2. = F(av)*change in t
2. Conservation of momentum
2.1. momentum is conserved if the net external forces on a system are zero
3. Collisions
3.1. Three Types
3.1.1. Elastic
3.1.1.1. Total kinetic energy is same before and after
3.1.2. Inelastic
3.1.2.1. final KE is less then the initial KE
3.1.3. Completely Inelastic
3.1.3.1. Completely stick together
3.1.3.2. Same as inelastic
3.2. In one dimensions
3.3. In two dimensions
4. Momentum
4.1. p=mv
4.2. kg*m/s
4.3. vector quanity
5. Newton's Second Law
5.1. F=lim (change of p)/(change of t)
6. Center of mass
6.1. Motion
6.1.1. P=Mv(cm)
