Hii its tom85

Angular velocity :-

The rate of change of angular position is called angular velocity .

  • angular velocity is denoted by omega .
  • si unit is rad/s.

Derivation of v=r*omega

let O be the center of a circle as well as origin of an axis .if the partical p describe by an angle theta.suppose it change its position to p' by an angle called theta das .The change in angle describe as delta theta .There must be in time difference that is delta t .

we know that

theta =L/r

where L is the distance travelled in circumstance of circle it must changes the change is denoted by delta S.

delta S=r*delta theta

so

delta s/delta t=r*delta theta /delta t

since delta s/delta t= v and delta theta/delta t=w

v=r*omega

hope it helps you dude
