Find the relation between surface tension and surface energy

Surface tension and surface energy are two very important concepts discussed in physics. The concepts of surface tension and surface energy are widely used in fields such as fluid mechanics, fluid dynamics, aerodynamics and various other fields. Surface tension is the net intermolecular force on the surface molecules of a liquid. Surface energy is the relevant energy of these bonds. In this article, we are going to discuss what surface tension and surface energy are, their applications, the definitions of surface tension and surface energy, their similarities, and finally the difference between surface tension and surface energy.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
