Question

A body of mass m executes uniform circular motion with speed v. After turning 60 degree what would be the change in velocity?​

Answer 1

For a constant mass and radius, the Fnet is proportional to the speed2. The factor by which the net force is altered is the square of the factor by which the speed is altered. Subsequently, if the speed of the object is doubled, the net force required for that object's circular motion is quadrupled.

Answer 2

Answer:

In uniform circular motion, angular velocity () is a vector quantity and is equal to the angular displacement (Δ, a vector quantity) divided by the change in time (Δ). Speed is equal to the arc length traveled (S) divided by the change in time (Δ), which is also equal to ||R.

Speed remains constant in uniform circular motion. A circular motion is the motion of a body in a circular path.

Explanation:

Objects moving in uniform circular motion will have a constant speed. ... The direction of the velocity vector is directed in the same direction that the object moves. Since an object is moving in a circle, its direction is continuously changing.
