What acts against the direction of motion and gets larger as an object moves faster?
Newton's second law
Terminal velocity
air resistance
16 N
When the net force is zero, the forces on an object are balanced.
If two forces are in the same direction, they cancel each other out.
Any time the forces are unbalanced, an object at rest will stay at rest until a net force acts upon it.
Force is equal to mass times acceleration.

F=ma
a=F/m
the speed an object reaches when the force of gravity is balanced by the force of air resistance

[static, sliding, rolling] friction keeps an object at rest .

Force always act in equal but opposite pairs.

force
friction
Friction brings most moving objects to a stop.
