Frames of reference

The following consequences can be derived about the perspective of an event in two reference frames, S and S, where S is travelling at a relative velocity of u to S.

• v'' = v - u (the velocity v' of a particle from the perspective of S is slower by u than its velocity v from the perspective of S)
• a' = a (the acceleration of a particle remains the same regardless of reference frame)
• F' = F (since F = ma) (the force on a particle remains the same regardless of reference frame; see Newton's law)
• the speed of light is not a constant

the form of Maxwell's equations is not preserved across reference frames
