Transcript

  1. Weight and terminal velocity
  2. objectives <ul><li>calculate an object’s weight </li></ul><ul><li>describe what terminal velocity is and how it comes about </li></ul><ul><li>draw and interpret velocity–time graphs for objects that reach terminal velocity </li></ul>
  3. starter <ul><li>what is the odd one out? </li></ul><ul><li>explain why. </li></ul><ul><li>kg g N lbs mg st oz </li></ul>
  4. Gravity and weight <ul><li>on Earth, there is 10N force on each 1kg mass </li></ul>weight (N) = mass (kg) x gravity (N/kg) what is your mass? what is your weight?
  5. 2 minute quick questions
  6. speed and drag
  7. <ul><li>http://www.bbc.co.uk/learningzone/clips/why-does-a-human-have-a-different-terminal-velocity-to-a-mouse/8751.html </li></ul>
  8. Terminal Velocity
  9.  
  10. <ul><li>exam q </li></ul>
  11. to finish with <ul><li>The _______________ of an object can be calculated using the equation: W = m x g. On Earth, this means the weight is 10 times the mass, as the Earth’s gravitational field _______________ is 10 N/kg. The faster a body moves through a fluid, the _______________ the frictional force on the object. A body falling through a fluid will _______________ at first because of its weight. This will increase the friction, so the resultant force will _______________ . It will continue to accelerate until it reaches a terminal velocity when the weight is balanced by the _______________ . </li></ul><ul><li>friction greater reduce strength weight accelerate </li></ul>
