Question

what relationship must exist between an applied force and the velocity of a moving obkect if uniform circular motion is to result

Answer 1

See explanation

Step-by-step explanation:

The centripetal force keeps an object moving in a circular orbit at constant velocity. The velocity of an object undergoing uniform motion is always tangential to the circle while the centripetal force is directed towards the center of the circle.

This now implies that the direction of the force acting on a body undergoing circular motion at constant velocity is perpendicular to the direction in which the object is being displaced.
