Final-Answer:
Friction is a force that opposes the relative motion of two objects or materials. It is caused by the interaction of the microscopic surface features of the two materials. The two factors that affect friction are the normal force and the coefficient of friction. The normal force is the force that is perpendicular to the surface of contact. The coefficient of friction is a measure of the roughness of the two surfaces. The higher the coefficient of friction, the greater the force of friction.
If Ram cannot move a box by applying force, it means that the force of friction is greater than the force that Ram is applying. This can happen if the box is very heavy, if the surface is very rough, or if the coefficient of friction is very high. To move the box, Ram will need to apply a greater force or reduce the force of friction. He can do this by making the surface smoother, by using a lubricant, or by applying the force at a different angle.
