Question

You whirl a stone in a horizontal circle in such a way that the stone is in uniform circular motion the following is true for this situation? (Select all that apply.) Which of The stone is moving with constant velocity The direction of the stone's velocity changes as it moves around the cirde. The change in direction of the stone's motion is due to the centripetal force acting on the stone. The magnitude of the stone's velocity does not change. The stone's speed is constant. Supporting Materials Physical Constants Additional Materials . Readins

Explanation / Answer

The statements that are true in this situation are

Answer)

1) The direction of the stone's velocity changes as it moves around the circle.

2) The change in direction of the stone's motion is due to the centripetal force acting on the stone

3) The magnitude of the stone's velocity does not change.

4) The stone's speed is constant

Reason : centripetal acceleration is responsible for the circular motion , it acts perpendicular to the velocity in the circular motion . So the centripetal acceleration changes the direction of velocity but not the magnitude

Speed is constant since direction is not involved only magnitude is involved

Magnitude of velocity in this situation remains constant
