Rotational Kinematics

Question	Answer
Fact #1	Displacement indicates how far an object ends up from its initial position, regardless of its total distance traveled.
Fact #2	Average velocity is displacement divided by the time interval over which that displacement occurred.
Fact #3	Instantaneous velocity is how fast an object is moving at a specific moment in time.
Fact #4	Angular displacement (theta) indicates the angle through which an object has rotated. It is measured in radians.
Fact #5	Average angular velocity  is angular displacement divided by the time interval over which that angular displacement occurred. It is measured in rad/s.
Fact #6	Angular Acceleration tells how much an object’s angular speed changes in one second. It is measured in rad/s per second.
Fact #7	Instantaneous angular velocity is how fast an object is rotating at a specific moment in time.
Fact #8	Angular acceleration and centripetal acceleration are independent. Angular acceleration changes an object’s rotational speed, while centripetal acceleration changes an object’s direction of motion.
