Defining axes

The perpendicular force resulting from the surface on which an object is resting

Normal force

F_N = F_g = mg

Tangent of the angle at which the object begins to slip

Friction

f = uF_N

Kinetic

Static

Origin of the circle

Uniform Motion or Rest

MOTION

Gravity

mg

GMm/R^2

Centripetal force

F_c=ma_c

Centripetal acceleration

a_c=v^2/R

a_c=4π^2Rf^2

a_c=4π^2R/T^2

Is a push or a pull

Third Law

Every action has an equal and opposite reaction

F_(a,b)=-F_(b,a)

Second Law

F=ma

Calculate the acceleration of a system

Tension Force

Is a force that prevents the stretching of objects

System of equations

Pullys

Change the direction of force

Atwood's Machine

g(m1-m2)/(m1+m2)

First Law

Inertia

Objects will remain in their original state of motion unless acted upon by an unbalanced external force
