simple one is: max friction = coefficient of static friction*normal force
Friction force hasn't a chemical formula.
An important formula is that friction = (coefficient of friction) x (normal force).
Friction force hasn't a chemical formula.
Ukn
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.
Friction.
You use the formula of finding force of friction. The eq'n is: Force of friction = the coefficient of friction multiplied by normal force.
It increases. Static friction is the friction that opposes an object at rest to begin moving, given the following formula :- Fs = MsN, where ms is the coefficient of static friction, and n is the normal force, which is equal to mg if is at the x-axis. As the formula shows, the static friction increases with an increase in mass.
f=6*pi*eta*r
f=6*pi*eta*r
There is friction nearly everywhere. Air resistance, carpet, and your shoes all produce friction. The formula for finding the force of friction is friction force equals the coefficient of friction times the cosine of the angle of the force times the mass of the object times gravity (9.80 meters/sec squared)
velocity times gravity times friction:)
