Question

A body moves around the sun with constant speed in a circular orbit. Is the motion of the body uniform or accelerated?

Answer 1

Step1: Given that:

In a circular orbit, a body moves at a constant speed around the sun.

Step 2: Finding the motion of the body uniform or accelerated:

1. Assume a body moves in a circular path at a constant speed. then it will have centripetal force.
2. After one complete circle, the body's velocity returns to its initial direction.
3. Then, when a body moves in a circular path at a constant speed, its direction changes. Then, the body's velocity changes.
4. When a body moves around the sun with constant speed in a circular orbit, the motion of the body is accelerated because its velocity changes by equal intervals of time.

Thus, The motion in a circular path is considered an accelerated motion.
