The linear variable of all particles are same in rotational motion of rigid body.

Explanation

Linear variables `vecr,vecv and veca` of all particles of rigid body are different in rotational motion, means they are not same.
Different particles have different position vectors `(vecr)`. Hence linear velocity `vecv=rvecomega` also different. The value of linear velocity of particle near to the axis is less the value of linear velocity of particle far from the axis because angular velocity `vecomega` is same for all particle and so in linear acceleration
`|veca|=sqrt(((v^(2))/(r))^(2)+(ralpha)^(2))` velocity changes. So it is not same.
