Assessments: open note test; investigation
Test date: to be arranged
| Week number | Starting date | Lesson content | Lesson resources and links | Homework |
| 33 | 11.8 | Forces are interactions between objects Forces are measured in newtons, N We write units in a precise way e.g. N, not n for newtons Units must be written like this or they will mean something else Measuring devices must be calibrated in order to measure accurately and correctlyWhat are forces? - discussion. How big is a newton? Using newtonmeters - calibration | Lesson notes: Friday group Friday group: weightlessness in the space station video | This form |
| 34 | 18.8 | Examples of forces -eg gravity, friction, air resistance
Can a rubber band be useful to measure forces? Revising the method for recording data - correct labelling etc. Scales and measurements discussion History of measurement: TED talk
NASA and their unit error
Types of friction
| 8.2 ppt Lesson notes Tuesday Friday Friction welding video | In your notebooks, explain in 50 -75 words what causes friction between two surfaces including the word 'particles' moving? |
| 35 | 25.8 | Friday group only | Friday group only Using Lego models pulled along friction blocks in order to measure static and dynamic friction, and to investigate if increasing surface area increases friction. Friday lesson notes | |
| 36 | 1.9 | Resultant forces. Newton's Law. Unchanging motion and steady speed or velocity. | Newton law Lesson notes Tuesday Lesson notes Friday Forces on a falling parachutist video | Watch this video as preparation for next lesson. There is no written task with this homework. |
| 37 | 8.9 | Speed calculations Distance-time graphs Velocity time graphs Converting units of velocity: m/s to km/h and vice versa | PPT The tortoise and the hare - 'speed' a real video! Usain Bolt 100m world record Kinematics of Usain Bolt's runs - detailed analysis Average speed cameras (single units) Also, this video on changing units might help you Lesson notes: Tuesday | Complete this sheet. Beware the mathematical trickery! Question 2 is hard to follow mathematically. Homework sheet answers |
