For a body moving with relativistic speed, if the velocity is doubled, then

If the speed of a rod moving at a relativistic speed is parllel , to its length is doubled,

When a rod moves at a relativistic speed v, its mass

A body of mass ‘m’ is moving with velocity ‘v’: If the velocity is doubled what will be its kinetic energy?

A body moving with uniform velocity

If the speed of a particle moving at a relativistic speed is doubled, its linear momentum will

If the speed of a particle moving at a relativistic speed is doubled, its linear momentum will

Can a body moving with uniform speed have nonuniform velocity?
