Abstract:

Keywords:

Absolute, circular, motion, velocity, speed, light, source.

Introduction:

We know that speed of light is absolute i.e. it does not depend upon speed of its source. This Article intends to explain what can be cause of absolute motion of any body in general.

Mathematical Model of Absolute Motion:

Suppose that a person in the train moving with velocity v throws a metal piece in the direction of train with velocity v, then as we know, velocity of metal piece with relative to observer on station will be v + v = 2v and if thrown in opposite direction of train with same velocity, velocity of metal piece with relative to observer on station will be v -v = 0. Clearly, velocity of metal piece is not absolute in this case. It depends upon speed of source i.e. train. But there is one situation in which velocity of metal piece must be absolute i.e. it must not depend upon speed of its source.

Consider rescue helicopter. Ends of blades of helicopter are rotating with linear velocity "v". This helicopter is stationary in air. Consider that small piece of metal in the ends of blade is broken and separated from blade. We know that this piece of metal will travel in tangential direction with velocity "v" with relative to observer on helipad or pilot of helicopter. Now consider that this helicopter is flying with speed "v". Remember that blades are rotating with linear velocity "v". Now in this situation if the piece of metal in the ends of blade is broken then it must travel with velocity v, be it with relative to observer on helipad or pilot of helicopter. Speed of source i.e. helicopter must not have any effect on velocity of metal piece. Why? This can be explained as follow.

If we say that speed of helicopter will affect velocity of metal piece as in case of train, then it means that if metal piece is travelling in the direction of motion of helicopter, velocity of metal piece will be v + v = 2v. And in the direction opposite to motion of helicopter, velocity of metal piece will be v -v = 0. This is unthinkable because as the metal piece was part of end of blade, it means that velocity of blade itself in the direction opposite to that of helicopter is zero . It means that range of linear velocity of blades is from 2v to 0. This situation will destabilize blades and eventually break apart. To begin with, blades will not rotate at all. But as we know, this does not happen.

Conclusion:

Velocity of blades of helicopter is independent of speed of helicopter itself. Hence it will have no effect on the velocity of metal piece when it travels in space. Whether the helicopter is moving or not, if the blades are rotating with constant linear velocity v, linear velocity of metal piece will always be v. In other words, velocity of metal piece in this case is absolute. Speed of it's source i.e. helicopter, does not affect its velocity.

Any body in circular motion do have absolute velocity. Motion of centre point of its centripetal force i.e. motion of its source does not affect velocity of body in circular motion.

We can use absolute velocity of body in circular motion to release spacecraft to cross Galaxies. If the spacecraft is rotating in space with linear velocity v, when released it will travel in any direction with velocity v. Speed of its source will have no effect on velocity of spacecraft.
