  1. Physics 5 Pressure and Moments

  2. C/WPressure6-Jun-14 Aims:- 4 describe pressure 5 explain pressure in a liquid or gas 6 calculate pressure

  3. FT Copy note then do … • Pressure is how spread-out a force is Complete worksheet then … Draw a design for either: • a stiletto with a low pressure heel • a football boot with high pressure studs

  4. IT Copy note then do … • Pressure is how spread-out a force is Complete worksheet

  5. IT Copy note then do … • Pressure in a liquid is caused by the weight of the liquid on top Watch demo – draw it, label it and explain what you see

  6. IT Copy note then do … • Pressure in a gas is caused by the gas particles hitting the sides of the container Answer questions a,b and 1 on pages 36-37

  7. HT Copy note then do … • Pressure is how spread-out a force is Pressure = Force ÷ Area N/m2 N m2 Now complete worksheet

  8. HT Copy note then do … • Pressure in a liquid is caused by the weight of the liquid on top • Pressure is the same throughout the liquid Copy hydraulic example diagram and calculation p34 Attempt worksheet

  9. HT Copy note then do … • Pressure in a gas is caused by the gas particles hitting the sides of the container Answer questions a,b and 1,3 on pages 36-37

  10. Are You On Target Today? Aims:- 4 describe pressure 5 explain pressure in a liquid or gas 6 calculate pressure

  11. C/WMoments6-Jun-14 Aims:- 4 describe what a moment is 5 explain balanced moments 6 calculate balancing moments

  12. FT Copy note then do … • A ‘moment’ is the turning effect of a force Complete Worksheet 1 (levers) Complete Worksheet 2 (see-saws)

  13. IT Copy note then do … • A ‘moment’ is the turning effect of a force Complete Worksheet 1 (levers)

  14. IT Copy note then do … • Moments are calculated using:- Moment = Force x Distance Nm N m Complete Worksheet 2 (balanced moments)

  15. HT Copy note then do … • A ‘moment’ is the turning effect of a force Complete Worksheet 1 (levers)

  16. HT Copy note then do … • Moments are calculated using:- Moment = Force x Distance Nm N m Complete Worksheet 2 (balanced moments)

  17. HT Copy note then do … • To find a balancing moment … Distance = Moment ÷ Force m Nm N Force = Moment ÷ Distance N Nm m Now do worksheet 3 (balancing moments)

  18. Are You On Target Today? Aims:- 4 describe what a moment is 5 explain balanced moments 6 calculate balancing moments
