Lesson details

Lesson outcome

I can draw force diagrams and identify pairs of forces that obey Newton’s Third Law.

Show transcript
Some forces require contact between objects, while others do not. Forces are vectors and can be drawn as arrows on diagrams. A free body diagram shows all of the individual forces acting on a single object. For every force there is an equal sized force acting in the opposite direction. Force pairs have the same magnitude and type and act in opposite directions between two objects.
