  1. What do a diplodocus and a tower crane have in common?

  2. 10 June, 2014 Moments • Objectives • Be able to describe what a moment is and be able to calculate moments.

  3. Outcomes ALL be able to describe what a moment is MOST be able to apply this to real life situations SOME be able to apply mathematically

  4. Moments A measure of the turning effect of a force

  5. Moments  • The distance is the perpendicular distance – the shortest distance between the line of action of the force and the pivot

  6. Context
