Torque () The moment of a force about an axis that produces an angular acceleration. Measured in N*m
The moment arm (r) is the perpendicular distance from the force to the axis of rotation. Measured in m
The force (F) is the component of the

Periodic Motion: Motion that repeats itself after a given period of time.
Period (T): Time it takes for one complete cycle
or
T=
Frequency (f): How often a cycle is repeated per unit of time
T=
or
f=
Simple Harmonic Motion:
Amplitude: Maximum

Force Push or pull
Law Scientific theory that has been proven for many years (can be changed)
Newton's 1st Law (Law of Inertia): Object at rest stays at rest while an object in motion continues in motion of a straight
line until acted on by a

Work: Product of force and displacement (scalar)
W = Fd
Work for the joules

Work is only done in the direction of the force!

If something is not moving, then there is no work being done (even if there is a force!)
