circular motion


 what is circular motion ?

A body is in motion in such a way that body is at equal distance from certain point then the body is said be in circular motion .
 
 * θ determine the position of particle during circular motion called angular position of the particle . 
ፀ = initial angular position of particle at time t 
Ө +△θ =  final angular position of particle at time t+🛆t
angular displacement = final angular position - initial angular position 
angular displacement of particle b/w time t and t+🛆t 
  ( Ө + Δ Ө )  -  ፀ  = Δ Ө 
        (Өf  - Өi )     = Δ Ө   
      
Average angular velocity -: 
It is defined as the ratio of total angular displacement to the total time taken 
Average angular of particle b/w t and t+△t = △θ/△t.
