A toy plane is connected to a string. You hold the free end of the string and whirl the plane horizontal circle in such a way that the plane is in uniform circular motion. Which of the following statements are true for this situation? (Select all that apply) i. The plane's speed is constant. ii. The direction of the plane's velocity changes as it moves around the circle. iii. The magnitude of the plane's velocity does not change. iv. The plane is moving with constant velocity. v. The change in direction of the plane's motion is due to the centripetal force acting on the plane.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
