Question 152: Work, Energy and Power & Circular Motion

Question

Which of the following statements is
FALSE
for a particle moving in a circle with a constant
angular speed?

Accepted Answer

Only option $$(b)$$ is false since acceleration vector acts along the radius of the circle or towards center of the circle for uniform circular motion and velocity vector always acts along the tangent of the circle.

Answer

The velocity vector is tangent to the circle.

Answer

The acceleration vector is tangent to the circle.

Answer

The acceleration vector points to the centre of the circle.

Answer
