Application of mechanics to the study of static equilibrium of rigid and elastic bodies. Topics includes composition and resolution of forces; moments and couples; equivalent force systems; free-body ...

In this diagram there are two forces, which, when added together give a resultant force of 30 newtons (N). Resultant force = 20 N + 10 N. Resultant force = 30 N to the right. 2.

There are four forces acting on this block: downward gravitational force, the force from the push, a frictional force, and a normal force from the wall. As a force diagram, it would look like this.

Multiple forces act on an object at the same time. Find out more with BBC Bitesize. For students between the ages of 11 and 14.
