Study Notes
Angular Measurement
- A radian is a unit of angular measurement defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.
Angular Displacement
- Angular displacement is the angle through which an object rotates from its initial to its final position.
Degree-Radian Relationship
- There is a fixed relationship between degrees and radians: 360 degrees is equivalent to 2π radians.
Direction of Rotational Motion
- In rotational motion, counterclockwise motion is considered positive, while clockwise motion is considered negative.
Angular Velocity
- Angular velocity is the rate of change of angular displacement with respect to time, measured in radians per second (rad/s).
