Ok so I am not so bad at physics but I find it hard to understand formular like how to use this one
mu *m*g=
I know its somewhat related to friction but what is the mu stand for and g too

IF someone could plzz translate these symbols to words I would really appreciat it

Sorry for english I know its not the best.
Or a link to a translation chart for physics symbols would do just fine

g is the acceleration of gravity, which is a measure of how strong gravity is. You need to multiply by g to convert mass (how much 'stuff' there is) to weight (how heavy it is). The value of g on earth is 9.8 m/s^2, or Newtons per kg. If g were zero, there would be no friction force.

"mu", which in textbooks is represented by the Greek letter µ , is the coefficient of friction. It is what you multiply the weight by to get the friction force, if the surface is level. For tilted surfaces you need another factor also.
