The correct answer is option 4) i.e. all of the above

CONCEPT:

  • Circular motion: The motion of an object along a circular path is called as circular motion.
  • Centripetal force: It is a net force acting on an object undergoing a circular path of motion, such that the force acts in a direction towards the centre of curvature.

​EXPLANATION:

  • A circle is assumed to be a polygon with infinitely many sides such that each side approximates to a point.
  • So, an object moving on a circular path undergoes a change in direction at every point. 
  • Since direction changes at every point, velocity changes at every point.
  • Also, a centripetal force always acts on an object under circular motion since it is the force that makes a body follow a curved path.
