Resonance 4 – Force and Motion

Resonance 4 covers the fourth module of high school physics (PHY4 Force and Motion). The module deals with uniform and variable motion. The module introduces force as an essential quantity describing the interactions between bodies, and examines how Newton's second law is used to model the effect of force on the change in the state of motion.
