Relativity H.1

H.1.1
Describe what is meant by a frame of reference.
The frame of reference illustrates the idea that the motion of an object is dependent on the P.O.V of the observer. For example, sat from my pov is not moving, however from the pov of space sat is moving incredibly fast as he is moving at the speed at which the planet he is on is rotating.
The point of view of an observer is called the frame of reference.

H. 1.2
Galilean Transformation is a method of mathematically quantifying the relative velocities of two objects in motion relative to each other. For example if you take an object travelling at 0.6c to the east and object travelling towards the other objects to the west then the Galilean transformation would be 1.2c. However this is wrong as the velocity exceeds the speed of light which is not possible.
