AS2.4 Mechanics (External)
Mechanics is referred to as classical Physics. The standard is worth 6 Credits. The following  topics  make up the standard.
Motion:
  • constant acceleration in a straight line
  • free fall under gravity
  • projectile
  • motion (constant speed with one force only providing centripetal force)
Force:
  • force components
  • vector addition of forces
  • unbalanced force and acceleration
  • equilibrium (balanced forces and torques)
  • centripetal force
  • force and extension of a spring. 
Momentum and Energy:
  • momentum
  • change in momentum in one dimension and impulse
  • impulse and force
  • conservation of momentum in one dimension
  • work, power and conservation of energy
  • elastic potential energy.
