CONCEPT:
- Uniform circular motion is where a moving object traces a circular path with constant speed.
- A circle is assumed to be a polygon with infinitely many sides such that each side approximates to a point.
- So, if the object moving on a circular path undergoes a change in direction at every point.
- Since direction changes and speed remains constant, velocity is varying at every point.
EXPLANATION:
- The child on the merry-go-round is under a uniform circular motion i.e. the child has a constant magnitude of velocity, but the direction of velocity changes at every point.
- A change in velocity is due to a change in magnitude or direction or both.
- Acceleration occurs if there is a rate of change of velocity.
- Since the child is moving with constant speed but the velocity changes, it is accelerated motion.
