4 gravity

  1. 1. Gravity
  2. 2. <ul><li>Gravity - the force that every object exerts on another object. </li></ul><ul><li>Ex: When you fall and hit the ground…you go “Boom.” </li></ul>
  3. 3. <ul><li>The amount of gravity between objects depends on 2 things. </li></ul><ul><li>Mass of the objects </li></ul><ul><li>Distance between the objects. </li></ul>
  4. 4. <ul><li>Weight - the measure of the force of gravity on an object. </li></ul><ul><li>-More mass = more weight </li></ul><ul><li>Weight is measured in 1.Newtons (N)…Metric system </li></ul><ul><li>2.Pounds (lbs)…English system </li></ul>
  5. 5. <ul><li>To calculate weight in lbs. </li></ul><ul><li>__lbs. X force of gravity = __lbs. </li></ul><ul><li> </li></ul><ul><li>Ex: How much would a 100 lb. person weight on Jupiter which force of gravity is 2.64? </li></ul><ul><li>100lbs. X 2.64 = 264 lbs. </li></ul>
  6. 6. <ul><li>To calculate weight in Newtons </li></ul><ul><li>___kg X force of gravity = ___N </li></ul><ul><li>Ex: How much would a 100 kg person weigh in Newtons on the moon which has a force of gravity of 1.6 N/kg? </li></ul><ul><li>100kg X 1.6 N/kg = 160 N </li></ul>
  7. 7. <ul><li>To calculate weight in Newtons when your starting weight is lbs. </li></ul><ul><li>___lbs / 2.2 = _____kg </li></ul><ul><li>___kg X force of gravity = ___N </li></ul>
  8. 8. <ul><li>Ex: How much would a 100 lb. person weigh in Newtons on Earth which has a force of gravity of 9.8 N/kg? </li></ul><ul><li>100lbs. / 2.2 = 45 kg </li></ul><ul><li>45 kg X 9.8 N/kg = 441 N </li></ul>
