Examples of two objects that rub together include rubbing a balloon against fabric to create static electricity or rubbing two sticks together to start a fire.
When we rub two objects together then heat energy is generated.
Gain or lose
It is called interlocking, where two objects become entwined or stuck together after a collision.
When two objects are rubbed together, friction is created. Friction is the force that resists the motion between two surfaces in contact. Rubbing two objects together can generate heat due to the friction produced between them.
Friction is the resistance to motion that occurs when two objects rub together. It is caused by the interactions between the surfaces of the objects, which create a force that opposes the motion.

If you rub two identically charged objects together, they will repel each other due to like charges. The objects will not stick together and may even push each other away.
Gravity pulls all objects that have mass together.
They attract.
When two objects rub together, the force of friction is generated due to the molecules on the surfaces interacting with each other. This force opposes the motion between the two objects and can result in heating, wear, or slowing down of the objects. The amount of friction depends on factors like the roughness of the surfaces and the force pressing them together.
When you rub two objects together, the kinetic energy from your motion is converted into thermal energy due to friction. This friction causes molecules in the objects to vibrate, generating heat energy.
Friction can be this, but it is also plainly two objects rubbing upon each other creating heat, or thermal energy. Anytime something rubs upon another, it doesn't ordinarily bond the two objects. For example, a toy car going up and down a toy track doesn't bond the two objects even though it creates friction between the wheels and the track.
