The force require to bend the normally straight path of a particle into a circular path is called_force.
Correct answer: D. Centripetal
- A. Travelling
- B. Centrifugal
- C. Bending
- D. Centripetal
Explanation
Option D is correct. The force required to bend the normally straight path of a particle into a circular path is called centripetal force. Centripetal force is always directed towards the centre of the circle and is perpendicular to the particle's velocity. This force is necessary to keep the particle moving in a circular path. The centripetal force is given by the following equation: Fc = mv²/r

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.
