infoWhy this? Momentum methods and models of elastic strings and springs allow us to analyse interactions and systems in which force varies with extension. Hooke's law and elastic potential energy connect deformation with force and energy transfer, developing our ability to select and combine appropriate mechanical principles.

scheduleWhy now? Returning to Year 12 momentum, work, and energy provides a secure starting point for introducing elastic potential energy and combining kinetic, gravitational, and elastic energy within a single problem. Revisiting momentum also prepares for the subsequent extension of collisions to two dimensions.
