Ignore?
Gravitational Field Strength
gravitational force per unit mass experienced by a mass placed at that point
Newton's Law of Gravitation
Every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Universal Gravitational Constant
F=g(m1m2/r^2) G = 6.67 E-11 N m² / kg²
Rotational Motion
Forces applied to an object cause the object to rotate around a fixed point (fulcrum)
Torque
A "force" that causes rotation because it is exerted at a distance from the axis of rotation.
tangential speed
The speed of an object moving along a circular path.
Fc=mv^2/r
formula for centripetal force
Ac=v^2/r
formula for centripetal acceleraton
Gm1m2 divided by r^2
formula for newton's law of universal gravitaton
Field Force
A force exerted on an object without touching it
T=1/F
formula for period
f=1/T
formula for frequency
formula for efficiency
