Unit for Force

Newton= kg*m/s^2

4

Units for Velocity

m/s

5

Units for acceleration

m/s^2

6

Velocity

V=displacement/time= d/t
speed= abs(V)

7

Acceleration

a=change in velocity/time=ΔV/t

8

Uniform Accelerated Motion (UAM)

constant a
variables: d, V, V0, a, t
given 3, find 1, other not involved
d=displacement

9

UAM Equation 2

V=V0 + at
missing displacement

10

UAM Equation 3

d=V0*t + (.5)a*t^2
missing V

11

UAM Equation 5

V^2=(V0)^2 + 2ad
