Contact forces are

Non contact forces are

Name two contact forces.

Suppose F,F_(N) & f are the magnitudes of the contact force, normal force and the frictional force exerted by one surface on the other, kept in contact, if none of these is zero :

Let F,F_N and f denote the magnitudes of the contact force, normal force and the friction exerted by one surface on the other kept in contact. If none of these is zero,

Physical force theory explains

Normal Force|| Stress and Strain

The contact force acting on a dropped body is
