Physicists like to represent forces on an object by drawing a Free Body Diagram. This is simply a representation of an object and a graphical representation of all the forces acting on that object.

Learn about Newton’s three laws, terminal velocity, contact and non-contact forces and free body diagrams with GCSE Bitesize Physics.

Free body diagrams Show the forces acting on an object in a free body diagram. The arrows represent the size and direction of the forces acting. When drawing a force diagram: ...

Learn how to use free-body diagrams to simplify mechanics problems involving multiple forces, objects, and motions. Follow four easy steps to identify, resolve, and apply the forces.

An extreme laboratory in space involving three dead stars has shown that all objects really do accelerate identically, proving Einstein right.
