The force exerted by surface tension on the free surface

The force due to surface tension is

The basic reason of the force of surface tension is the tendency of the surface of a liquid to ___.

The total force exerted by a body normal to the surface is a called____.

The force of surface tension acts tangentially to surface whereas the force due to air pressure perpendicularly on the surface. How is then due to excess pressure inside a bubble bal force due to the surface tension ?

When a person walks on a rought surface, the frictional force exerted by surface on the porson is opposite to the direction of his motion. It is the force exerted by the road on the person that causes the motion.
