The linear variable of all particles are same in rotational motion of

1.	The linear variable of all particles are same in rotational motion of rigid body.
Answer» Solution :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.
