Question

multiple choice question
uniform circular motion is the movement of an object at a constant speed around a circle with a fixed

projectile path
radius.
velocity
net force.

Explanation:

Uniform circular motion is defined as the motion of an object moving at a constant speed around a circle with a fixed radius. A projectile path is for objects in projectile motion (not circular). Velocity in uniform circular motion changes direction (so not constant in the vector sense here). Net - force is centripetal force but the key defining geometric feature is the radius.

Answer:

radius.
