FRICTION is the force that two objects exert on each other when they rub against

each other.
Friction depends on 2 things:
1. How hard the two objects push on one another
2. The types of surfaces (smooth, rough)
There are 4 types of friction:
1. Static Friction- acts on an objects that AREN’T moving. This means
that you must use extra force to start the motion of a still object
2. Sliding Friction- When two solid surfaces slide over each other
example: your book sliding over your desk
3. Rolling Friction- When an object rolls across a surface. This is
easier to overcome that sliding friction
example: a car’s wheels rolling over the pavement
4. Fluid Friction- When a solid objet moves through a fluid.
(water, oil, air)
example: Moving your hand through the air
