Force of static friction between any two surfaces is given by: Ff=Us*N
How do you find the mass of the coin(m), gravity(g) (9.8m/sec2) and the angle (30) the flat surface makes with the table; Ff=m.g.sin0 and N=m.g.cos0
using the above expressions of Ff and N and the definition of the force of static fricition,show that the coefficient of static friction: Us=tan0=?
Mass=m will cancel out from the equations, so mass can be calculated only when the magnitude of the force is ...
The coefficient of static friction is examined. How you find the mass, gravity and angle of a coin on a flat surface is determined with calculations.
