Forces, vectors, and resultant force

Free-body diagrams of a box with a 12 N pull, 5 N friction, balanced vertical forces, and a skydiver at terminal velocity with weight and air resistance balanced A force is a push or pull that can change an object's speed, direction, or shape, and it is measured in newtons, N\text{N}N. Force is a vector, so both size and direction matter.
