Velocity on a rotating disk refers to the speed at which a point on the disk is moving as it rotates around its center. It is measured in distance per unit time, such as meters per second.
The velocity on a rotating disk can be calculated by dividing the circumference of the disk by the time it takes for one revolution. This is known as tangential velocity and is expressed as V = 2πr/T, where r is the radius of the disk and T is the time for one revolution.
No, velocity on a rotating disk is not constant. As the disk rotates, the distance between a point on the disk and the center changes, resulting in a change in velocity. The velocity at any given point is constantly changing in magnitude and direction.
The larger the radius of a rotating disk, the faster the tangential velocity will be. This is because a point on the outer edge of the disk has to travel a greater distance in the same amount of time compared to a point on the inner edge of the disk.
Tangential velocity refers to the speed at which a point on a rotating disk is moving along its circular path, while angular velocity refers to the rate at which the disk is rotating around its center. They are related by the equation V = ωr, where V is tangential velocity, ω is angular velocity, and r is the radius of the disk.
