Question

Motion of planets around sun is an example of ____.

• A. accelerated, non-uniform motion
• B. accelerated, uniform motion
• C. constant velocity, uniform motion
• D. none of these

Answer 1

The correct option is B

accelerated, uniform motion

Since the direction of the velocity is changing at each point, it will be considered as a circular accelerated motion.

But, the magnitude of the speed remains constant as there no change in speed (only direction changes)

So, it will be a uniform motion.

Uniform motion can produce acceleration only when the object is in a circular motion.
