A child is riding in a merry-go-round that moves at a constant speed. Then, the child is:

Complete the sentence with the correct option.

A moving object in uniform circular motion follows a circular path at a constant speed.

A circle is assumed to be a polygon with an infinite number of sides, each of which approximates a point.

So, an object moving in a circular path changes direction at each point.

Because the direction changes while the speed remains constant, velocity varies at each point.

The child on the merry-go-round is in a uniform circular motion, which means that the magnitude of velocity is constant but the direction of velocity changes at each point.

A change in velocity occurs as a result of a change in magnitude, direction, or both.

If there is a rate of change in velocity, there is acceleration.

It is accelerated motion because the child is moving at a constant speed but the velocity changes.
