  • 8 Questions around this concept.

Solve by difficulty

A particle moves in a circle of radius 5 cm with constant speed and time period 0.2 \pi s. The acceleration of the particle is

If a body moving in a circular path maintains constant speed of 10 ms-1, then which of the following correctly describes relation between acceleration and radius ?

An annular ring with inner and outer radii  R1 and R2 is rolling without slipping with a uniform angular speed. The ratio of the forces experienced by the two particles situated on the inner and outer parts of the ring ,F1/Fis ,

Concepts Covered - 1

Centripetal Force and Centrifugal Force
  1. Centripetal Force-

  • Force acts on the body along the radius and towards the center.

    

F=4m\pi^{2}n^{2}r

F=\frac {4m\pi^{2}n^{2}r} {T^{2}} 

Where

F = Centripetal force

\omega= Angular velocity

n = frequency

  1. Centrifugal Force  

  • It is a fictitious force which has significance only in the rotating frame of reference.

  • It is an Imaginary force due to incorporated effects of inertia.
