Radians per second

Definition

Radians per second is a unit used to measure angular velocity, which represents the rate at which an object rotates or moves in a circular path. It measures the change in angle (in radians) that occurs in one second.

Analogy

Imagine you are sitting on a spinning chair and someone starts spinning you around. The number of radians per second would represent how fast you are rotating. If you rotate 2π radians in one second, that means you complete one full rotation every second.

Revolutions per minute (RPM): RPM is another unit used to measure rotational speed, representing the number of complete revolutions an object makes in one minute.

Tangential Velocity: Tangential velocity refers to the linear speed of an object moving along a circular path, measured in units such as meters per second.
