Question

Is circular motion an acceleration motion?

Answer 1

Explanation:

1. Uniformly accelerated motion is defined as a particle's velocity increasing by the same amount at equal periods of time.
2. When a body is moving uniformly in a circle, its speed stays the same or is constant, but the direction of its velocity changes over time.
3. Acceleration is the term used to describe how a body's direction of motion changes over time.
4. A particle's acceleration is defined as the rate at which its velocity changes over time, or the change in velocity per unit of time. So a circular motion that is constant is an accelerated motion.

Hence, continuous changes in motion direction characterize a circular motion. When the direction changes, the velocity also does. Circular motion is therefore an accelerated motion.
