1. Use equations below in order to do Linear Motion problems.
Equation 1: Speed, average speed, or velocity = d/t
Equation 2: Acceleration (a) = (V2 V1)/ (T2- T1)
Equation 3: At rest, V1= T1= 0: a = V/T - V = at
Equation 4: a = g (10 m/s2, starting at res

Summary, and Study Guide
Momentum
Momentum is defined as: Momentum = Mass * Velocity
Velocity is a vector
Mass is a scalar
Momentum is a vector
When a scalar is multiplied times a vector the result is a vector
In order to change the momentum of

Property of moving things
Means inertia in motion
Review
Mass is a measure of the inertia an object has that is the resistance to changes in motion
Mass is a property
Newtons second law relates force mass and acceleration
