1. rubbing your hands together to keep warm in winter
2. the parts of a car engine rubbing together causes it to overheat sometimes
3. rubbing sticks together to make fire (it takes about two horus, but the stick gets hot)

1.when we have earth quakes
2.when you rub yor hands together
3. when you rub your feet on a rug
4. when you srub (while cleaning)
5. when walking you rub your legs
When atoms come close to one another, the atoms with the greater number of valence electrons push away the atoms with the lesser number of valence electrons. Many textbooks state that electrostatic charges cause friction, but these charges are simply another effect due to friction. Another reason friction is created is the heat that is released when atoms bond together. Also, when sliding one surface on top of another, bonds are constantly being broken.

up thrust, friction, air resistance, gravity and that's all i know
air friction also called air resistance or drag solid friction which is just normal friction and liquid friction like hydro-dynamics

Examples of SLIDING FRICTION is pushing a heavy rock in your path, or moving a box on the floor.
The fact that you can walk without sliding is an example of friction.
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.

Examples of fluid friction are fish swimming through water, an airplane flying through the air and a motorboat skidding over water. Although fluid friction refers to friction through water, it can also apply to air.
