For an object moving in a circle, the angle between linear velocity and the position vector is _.

Correct answer: C. 90 degrees

  • A. 0 degrees
  • B. 30 degrees
  • C. 90 degrees
  • D. 60 degrees

Explanation

The direction of angular velocity is tangent to the circle and the direction of the position vector is towards the center. As we know radius and tangent form a 90° angle, so the angle between linear velocity and position vector is 90°.

About Angular and Linear Quantities

Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
