balanced forces equal forces acting on an object in opposite direction, doesn't move the object
friction the force that two surfaces exert on each other when they rub against each other
static friction a type of friction that acts on objects not moving
sliding friction friction that occurs when solid surfaces slide over each other
rolling friction friction that occurs when an object rolls over each other
fluid friction friction that results when an object moves through a fluid
gravity the force that pulls objects towards each other
mass measure of the amount of matter in an object
weight the force of gravity on a person or object on the surface of a plane
air resistance a type of fluid friction, usually has to do with moving through the air
