can someone please explain me the differences between angular, rotational, translational and tangential vecoity pls. I am struggling to understand how their differ from each other and how they are caluclated.
When measured in cycles or rotations per unit time (e.g. revolutions per minute), it is often called the rotational velocity and its magnitude the rotational speed
Angular velocity is a measure of the rate at which an object rotates around a fixed point. It is typically measured in radians per second or degrees per second.
Rotational velocity is the speed at which an object rotates around its own axis. It is often used interchangeably with angular velocity, but can also refer to the velocity of a point on a rotating object.
Translational velocity is the speed at which an object moves in a straight line. It is typically measured in meters per second or feet per second.
Tangential velocity is the speed at which an object moves along a circular path. It is always perpendicular to the radius of the circle at any given point.
Angular velocity, rotational velocity, translational velocity, and tangential velocity are all related through the formula v = ωr, where v is the tangential velocity, ω is the angular velocity, and r is the radius of the circular path. This means that as the angular velocity increases, so does the tangential velocity.
