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

What is the acceleration of a piece of dust on an old-fashioned record album, 15 cm
from the center, if the record is spinning at 33.3 rpm?
Answer: 1.82 m/s/s. To find a

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
