Question

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

Answer 1

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.

Thank u so much!!
