Question

an object is undergoing a uniform circular motion, what can one say about its velocity? multiple choice the velocity has a constant magnitude, but its direction changes continuously. the velocity is constant in both magnitude and direction. the velocity has a constant direction, but its magnitude changes continuously. the velocity is constantly increasing in magnitude while maintaining its direction.

Explanation:

In uniform circular motion, "uniform" means the speed (magnitude of velocity) is constant. Velocity is a vector with magnitude and direction. The object moves tangent to the circle, so direction changes continuously (tangent direction at each point is different). So the velocity's magnitude is constant, direction changes.

Answer:

The velocity has a constant magnitude, but its direction changes continuously.
