Learning Goals

Learning Goals

At the end of the module students should be able to:

Motion

  1. define the terms
    • speed
    • velocity
    • displacement
    • acceleration
  2. plot and interpret distance-time graphs from results obtained from experiments
  3. plot and interpret various graphs representing and involving motion e.g. distance versus angel of slope
  4. calculate the distance traveled at constant speed using, distace = speed x time
  5. calculate speed from experimental observations of distance and time
  6. plot and interpret speed-time graphs using results obtained experimentally
  7. calculate acceleration using the formula, acceleration = (new speed - old speed) / time

Machines

  1. explain the term gear ratio
  2. perform experiments to show how gear ratio affects speed
  3. describe qualitatively how the weight that can be lifted is affected by gear ratio
  4. describe qualitatively how the speed at which a mass is lifted is affected by gear ratio
  5. plot and interpret graphs of speed at which mass is lifted versus the gear ratio

Forces

  1. describe what a force does to a body i.e. causes
    • change of shape
    • change of direction
    • change of speed
  2. graph the relation between forces and power level for a Lego robot
