Supersonic is fater than sound. Mach 1 is the speed of sound. Mach 2 is twice the speed of sound etc..

Basically every speed higher than Mach 1 is supersonic.

Thanks, for letting me know.

The English language isn't that hard to understand, super means higher or larger and sonic is to do with sounds.

I know but wasn't 100% with the mach part of it.

Mach is a bit of an odd term. It is named after an Austrian physicist Ernst Mach. It is also not a 'unit of measure'. A unit of measure is something like a metre. It is unchanging. A 'Mach number' changes depending on what substance it is referring too. For example Mach 1 in Earth's atmosphere is different to what Mach 1 would be in Mars's atmosphere.

Yeh, a bit like the Imperial system of measurement, hard to follow at times!

It's not actually a measurement, it's a dimensionless quantity. (this is just me being pedantic )
