Forces, vectors and resultants

Free-body diagrams of a book on a table, a box with a 12 N push and 5 N friction, and a falling ball at terminal velocity with forces labelled

A force is a push or pull caused by an interaction between objects, and it is measured in newtons, N. Force is a vector, so size and direction both matter.
