Video and lesson investigations on the topic of forces . Key concepts include:
- Pushing, pulling, bending and twisting are the names we give to actions that can result in several different forces action on an object.
- Strictly speaking, these actions are not the forces themselves, but actions that happen because of forces.
- Understanding what forces are and the part they play in making things move is difficult, involving a complex set of ideas.

All movement happens because of a force or combination of forces. Through their pushes and pulls they cause things, or objects to start moving,speed up, change direction, change shape or stop moving.
