Expert Film: Jon Badgery talks about forces acting in one dimension and how they can be represented using force arrows.

This video explores the concepts of balanced and unbalanced forces using pulley systems and weights, illustrating how forces in one dimension can be represented with arrows and measured in Newtons. It demonstrates how systems in equilibrium involve equal forces on both sides, and how removing or changing weights affects the balance, simplifying the understanding of force interactions. Learners will gain a clear visual and conceptual grasp of how forces act in one dimension and how to effectively represent them in different scenarios.
