Question

A body goes round with a constant speed in a circular orbit. Is the motion uniform or accelerated?

Answer 1

Step 1: Given data

In a circular orbit, a body rotates at a constant speed.

Step 2: Finding the motion uniform or accelerated

1. When a body moves in a circular motion with a constant speed it is called uniform circular motion.
2. As in uniform circular motion, the velocity changes at every instant due to which it becomes an accelerated motion.

Hence, if a body goes round at a constant speed in a circular orbit. The motion will be accelerated.
