Subject outcome

Subject outcome 2.2: State, explain, interpret and apply momentum and force

Learning outcomes

  • Define and calculate momentum and calculate the change of momentum of an object.
  • Define impulse ([latex]\scriptsize {{F}_{{nett}}}\cdot t[/latex]) as the change in momentum and use [latex]\scriptsize {{F}_{{nett}}}\cdot \Delta t=m\cdot \Delta v[/latex] for calculations and problem solving.
  • Define Newton’s third law and identify examples of interacting objects that exert equal forces on each other.
  • Define the law of conservation of momentum.
  • Identify and distinguish between elastic and inelastic collisions; and apply law using calculations.
