Rotational Motion AP Physics C

Definitions and Formulas

Example 1 A) What is the linear speed of a child seated 1.2 m from the center of a steadily rotating merry-go- round that makes one complete revolution in 4.0 s? B) What is her acceleration?

Angular equivalent equations for uniformly accelerated rotational motion Linear EquationAngular Equivalent

Angular acceleration of an object (such as a door) depends not only on the force, but the perpendicular distance from the axis of rotation to the line along which the force acts. This distance is called the lever arm or moment arm.

Two methods of calculating torque r
