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