Transcript of "Mass And Weight"

  1. 1. Mass and weight
  2. 2. Isaac Newton Responsible for defining mass in terms of force A fat dog
  3. 3. Simon says: A conversation between Simons Weight is a force but the kilogram is a unit of mass. You wouldn’t talk about a mass of a metre, or a weight of 20 joules. Don’t mix up quantities and the wrong units. My weight is 90 kilograms Cheryl Cole is always using kilograms to talk about her weight. You mustn't tell anyone that I told you, but she failed GCSE Physics And yet she still has an successful career as a musician with credibility and a great marriage – is there really more to life than GCSE Physics?
  4. 4. Everyone is laughing at my weight! They say the units are wrong! Apparently my mass is 105 kg, (a Nun’s habit is slimming look). My weight is about 1000 N and if I move to Jupiter my mass will stay the same but my weight will be about 300,000 N. I wish I’d listened more in physics lessons. I wish I could have been a physics teacher! Let me make some calls – I’ll find out what’s going on here
  5. 5. Enter someone with some sense… ..who asks an intelligent question. What is the connection between mass and weight?
  6. 6. Different objects Same force
  7. 7. Let them go! Acceleration and mass The more mass you have the less you accelerate when a particular force is applied.
  8. 8. Mass tells me how much stuff there is. The more mass there is then the less acceleration I get when I apply a certain force. Sorted!
  9. 9. Hold it, Po! What about the practical that we did in Year 7. Didn’t we hang masses on a Newton-meter and get a nice straight line? I though mass was to do with gravity? Forgot about Dre
  10. 11. Context Gravitation and mass The more mass you have, the more you are pulled towards other objects that have mass, (most importantly, the massive lump of rock you’re standing on).
  11. 12. Gravitation and mass The more mass you have, the more you are pulled towards other objects that have mass, (most importantly, the massive lump of rock you’re standing on). Acceleration and mass The more mass you have the less you accelerate when a particular force is applied.
  12. 13. Who has more weight? What does this mean? Who has more mass? Who will accelerate more? Let them go! Why is their acceleration the same? Can you explain it with ideas about mass and weight?
  13. 14. Weight in physics means the force of the planet that you are on pulling you towards its centre, Why is Cheryl’s weight more on Jupiter?
