Question

An object is rotating with constant angular velocity about a fixed axis. Consider a point 'P' on the body. Which of the following do/does not change with time?​

Answer 1

Answer:

. In more advanced studies of rotational motion, the angular velocity of a rotating object is defined in such a way that it is a vector quantity. For an object rotating counterclockwise about a fixed axis, this vector has magnitude ω and points outward along the axis of rotation.

Answer 2

An object rotates along a fixed axis at a constant angular velocity. A point P is considered on the body.

Because the body rotates at a constant angular velocity, point P moves at a constant speed with no linear or tangential acceleration. As a result, speed of P does not change over time.
