Static friction is the force that prevents two surfaces from sliding against each other when there is no relative motion between them.
The formula for calculating static friction is μsN, where μs is the coefficient of static friction and N is the normal force acting perpendicular to the surface.
The coefficient of static friction is affected by the types of surfaces in contact, the roughness of the surfaces, and the force pressing the surfaces together.
Yes, the mass of the block can indirectly affect the static friction by influencing the normal force acting on the block.
To find the mass of a block from static friction, you can rearrange the formula for static friction to solve for the mass, which would be m = F/μsN. You would need to know the applied force and the coefficient of static friction between the two surfaces.
