Uniform Circular Motion, Newton’s Law of Gravitation, and Rotational Motion-Princeton AP Physics I

Uniform circular motion

the object's speed around its path to be constant

centripetal acceleration

The acceleration vector points toward the center of the circle

Gravitational force

any two objects in the universe exert an attractive force on each other

Torque

the measure of a force’s effectiveness at making an object spin or rotate.

Center of Mass

the point where we consider all the mass of the object to be concentrated
