The centripetal acceleration of a body moving in a circle of radius r with uniform speed v is directed:
- A.Along the tangent, in the direction of motion
- B.Towards the centre of the circle
- C.Away from the centre of the circle
- D.Vertically downward
Show answer
In uniform circular motion the magnitude of the velocity does not change, so the acceleration can have no component along the direction of motion; the whole of it is perpendicular to the velocity and points to the centre, which is why it is called centripetal, meaning centre seeking, and its…
