Answer to Question #96014 in Mechanics | Relativity for Lauren Teehan

Question

A ball at the end of a string is swung in a horizontal circle above a person's head at a speed of 2.0 m/s. Is the ball undergoing uniform motion?

Answer 1

No. The uniform motion is the motion of an object in which the object travels in a straight line and its velocity remains constant along that line. But in this case the path is not a straight line but a circle and the velocity every time changes because the direction of motion changes too.
