Will the friction act on a body at rest. Do not take in the case of inclined plane.
As Halls' says, there's no friction acting in this case.Nstraw said:Well just consider a man standing.
Friction is the force that resists the relative motion or tendency of motion between two surfaces in contact.
Friction is caused by the microscopic irregularities and adhesion between the surfaces of two objects in contact.
Friction can prevent a body at rest from moving, as it requires a certain amount of force to overcome the resistance caused by friction.
Friction can be reduced by using lubricants or by polishing the surfaces in contact. However, it cannot be completely eliminated.
The three types of friction are static friction, kinetic friction, and rolling friction. Static friction occurs when two surfaces are not in motion relative to each other. Kinetic friction occurs when two surfaces are in motion relative to each other. Rolling friction occurs when an object rolls over a surface.
