Chapter 1-2 (Introduciton and Motion in One Dimension)
x=vt
x=1/2at^2 + Vi(t) (works well with no initial velocity)
Vf^2 = Vi^2 + 2ax
Vf = Vi + at
Average Velocity = (Vf + Vi)/2 (constant acceleration)
Chapter 3 (Vectors and Two-Dimensional Motion)
(Lowercase is a side/length; Uppercase is an angle)
Law of Cosines
a^2 = b^2 + c^2 - 2bcCosA
b^2 = a^2 + c^2 - 2acCosB
c^2 = a^2 + b^2 - 2abCosC
Law of Sines
SinA/a = SinB/b = SinC/c
Chapter 4 (The Laws of Motion)
Newtons 2nd Law: F=ma
Force is measure in Newtons = kg x m/s^2
Force of Weight (weight of object): Fw = mg (mass x acceleration of gravity) *Always to center of Earth*
