Whats is the difference of Lorentz and Galilean transformation?

Question

I am just confused. Don't be so technical. Thanks

Answer 1

The non-technical answer is the Lorentz transformation takes into account the effects of speeds close to the speed of light.  

Answer 2

In the Galilean transformation, only the spatial coordinates are transformed.  Time is not transformed.

In the Lorentz transformation, time is transformed along with the spatial coordinates.  

Answer 3

For relative speeds much less than the speed of light, the Lorentz transformations reduce to the Galilean transformation.

So:

For speeds much less than the speed of light we use Galilean transformation.

For speeds near the speed of light we use Lorentz transformations.

Answer 4

The latter is when you just subtract velocities of objects from that of the transformed frame to get the velocities in the new frame. Space and time intervals between events are not altered. A consequence is that Maxwell's equations for electromagnetism end up being valid only is some preferred (presumably "stationary") frame. The former changes such space-time intervals in such a way as to render the speed of light the same for all observers. Maxwell's equations are valid in all frames.

Answer 5

We use Galilean transformation when we work with normal velocity like that we experience daily

We use Lorentz transformation when we deal with velocities near the light speed such as c , 0,90 c , 0,80 c
