Linear Momentum
by Mary Lager
# Linear Momentum

## Momentum

### p=mv

### kg*m/s

### vector quanity

## Impulse Momentum Theorem

### change in p=sum of the F*change of t

### the change in momentum equals the impulse

### Impusle

## Newton's Second Law

### F=lim (change of p)/(change of t)

## Conservation of momentum

### momentum is conserved if the net external forces on a system are zero

## Center of mass

### Motion

### multiple equations pg. 234

## Collisions

### Three Types

### In one dimensions

### In two dimensions

N*s

= F(av)*change in t

P=Mv(cm)

Elastic, Total kinetic energy is same before and after

Inelastic, final KE is less then the initial KE

Completely Inelastic, Completely stick together, Same as inelastic
