Question

A satellite goes around Earth in a circular orbit at a constant speed .Is its motion accelerating ?

Answer 1

1. Acceleration is the rate of change of velocity in unit time.
2. Acceleration =$\frac{changeinvelocity}{timeinterval}$.
3. A satellite is moving with uniform speed in circular orbit but its direction of motion is changing at every point.
4. Hence, velocity changes at every point and which means that the motion is accelerated.

Hence, the motion of a satellite around the earth is accelerated motion.
