Force
From AoPSWiki
A force, defined informally, is a "push or pull" on a physical body. The SI unit for force is the newton. Force has direction as well as magnitude, meaning it's a vector.
Formal Definition
A force is that which may cause a physical body with mass to accelerate in a given direction. If the forces acting upon a body cancel out, then the body is in equilibrium and does not accelerate.
