Newton’s first law
An object will remain in its current state of motion (at rest or moving) unless acted upon by a nonzero external force.
Inertia
An objects resistance to change in motion. Directly proportional to the objects mass.
Newton’s second law
A={f/m
The direction of the acceleration is the direction of the net force acting on the object.
Newton’s third law
Every object that applies a force will have an equal and opposite force applied to it.
Sum if the forces in one dimension
{f=f(net)=ma
Radial acceleration
Ac=v^2/r
Period and frequency
F=1/t
T=1/f
Force of friction
Ffriction=uFn
Universal law of gravitation
Fg=(Gm1m2)/r^2
Potential energy from gravitation
Ug=(Gm1m2)/r
Work
W=Fdcos(theta)
Work is only done if the distance traveled is parallel to the force acting on an object.
