Question

a clown on a unicycle is riding in a circle at a constant speed. which statement describes the clowns motion? the clown has a constant velocity. the clown is accelerating.

Explanation:

Step1: Recall velocity and acceleration concepts

Velocity is a vector (has magnitude - speed and direction). Acceleration is the rate of change of velocity.

Step2: Analyze circular - motion

When an object moves in a circle at a constant speed, its direction is constantly changing. Since velocity is a vector and direction is changing, the velocity is changing. A change in velocity means there is acceleration.

Answer:

The clown is accelerating.
