WebHow do you find the mass of coefficient of friction? The mass can be found using the equation F grav = m * g. Using mu = F frict / F norm, mu = (10 N) / (100 N) = 0.1. The F net is the vector sum of all the forces: 100 N, up plus 100 N, down equals 0 N. And 20 N, right plus 10 N, left = 10 N, right. WebStatic friction is the force of friction on an object that is not moving. If you push on a stationary block and it doesn't move, it is being held by static friction which is equal and opposite to your push. Once your push exceeds the maximum possible static friction (budging force = μN), then the block will start moving. list of 6 syllable words
