Question

When is an object moving in uniform circular motion?

A. when it speeds up around a curve
B. when its tangential speed is constant
C. when it has no net force acting on it
D. when its acceleration is tangent to a circle

Answer 1

B:when its tangential speed is constant

Although the speed of an object that has a uniform circular motion is constant, its velocity is not constant. Not only that, but it is actually changing constantly.
