Free-body diagrams, Newton's three laws, weight, friction and resolving forces on inclines.
A force is a push or pull (a vector, in newtons). The motion of any object is governed by the resultant of the forces acting on it.
Newton's laws
- An object stays at rest or moves at constant velocity unless acted on by a resultant force.
- — resultant force = mass × acceleration.
- Every action has an equal and opposite reaction (on a different body).
