  1. 8 MAPPING SPACE AND TIME / 9 COMPUTING THE NEXT MOVEScalars and vectors • Learn definitions of these terms • Add and resolve vectors to solve problems

  2. Equations of accelerated motion • Derive and use the suvat equations for uniformly accelerated motion

  3. Newton’s second law of motion • Derive the equation F = ma • Explain observations of falling bodies in terms of this equation • Solve problems using F = ma

  4. Parabolic motion • Describe and explain the trajectory of an object projected in a uniform gravitational field

  5. Measuring g • Determine the acceleration due to gravity experimentally • Learn how graphical analysis methods can be used to eliminate systematic errors

  6. Acceleration on slopes • Analyse experimental data to determine g by another method

  7. Air resistance • Investigate the factors affecting drag forces in fluids • Explain the motion of falling objects in terms of gravity and drag forces acting

  8. Energy and motion • Derive expressions for gravitational potential energy and kinetic energy • Solve motion problems using energy considerations

  9. How fast can a party popper launch a ping pong ball into the air? • Can you & partner devise a simple method to estimate the speed at which a party popper launches a ping pong ball into the air? • You have access to a clamp stand, party poppers with the streamers removed, ping pong ball, metre stick and safety glasses • What assumption do you need to make?

  10. Work, energy and power • Explain braking distances for vehicles in terms of energy changes • Derive an expression for mechanical power

  11. Relative velocity • Use ideas about relative velocity to solve motion problems that involve compass headings/bearings

  12. Collision avoidance • Learn how to determine if two moving objects are on a collision course

  13. Modelling of motion • Use algorithms and software tools to model motion
