What causes heat energy when you rub two objects against each other?(2 points) The air around the objects

The flow of heat from one object to the other

The friction between the two objects

The pull of gravity on the two objects

Explanation:

It's easy- They produce heat because the surfaces on small scales are rough like canyons rather than flat like the ocean. As these rough surfaces come into contact with each other they repel. When two atoms are brought very close together they store potential energy. When they move apart that energy becomes kinetic.
