Weight and MASS
What we want to achieve....
• Be able to recall the difference between
  mass and weight
• Be able to calculate you weight on other
  planets
• Be able to describe why the value of
  gravity is different on different planets
Brainstorm, what do we already know
about gravity?




             Gravity
Newton is famous for his theory of gravity

                He actually worked out how the mathematics or the ‘rules or gravity’

                The rules of Gravity affect everything that has mass so that means
                You, books, calculators, the planets, stars and teachers.


                      All masses are attracted to each other


   The force of gravity depends on the distance between the two masses and the
                         Size (magnitude) of the two masses


FORCE is measured in NEWTONS (N)


           He is famous for the apple story

           Although this probably never happened
Gravity pull all objects down at the same rate

Air resistance will slow some object but there is no air on the moon so...
MASS and WEIGHT are NOT the same thing!!!!!!!!!!
           120kg                       120kg x 10 = 1200 N



                                                                      x Gravity


Mass is the same wherever you are as it is the amount of stuff (particles) that are in you


   Weight is your mass multiplied by the gravitational pull of the planet you are on


                On Earth your weight is roughly 10x your mass


            Your weight is a force and is measured in Newtons
On the moon the gravitational force is 6 time less than on Earth
              120kg                       120kg x 1.6 = 200N



                                                                        x Gravity




This is because the moon has 1/6 less mass than the Earth it has 1/6 less gravitational pull

The man has lost weight by going to the moon but what about his mass?
If you know your weight in KG you can use that, otherwise use 50KG as your mass

           Place                Weight of 1Kg              Calculation           Your weight (N)
           Earth                    10N
           Mars                      4N
          Jupiter                   23N
           Pluto                     3N
          Uranus                    11N
          Venus                      9N
         Neptune                   10.6N
       On the moon                  0.1N
       In deep space                 0N


              Copy into your book the table above and calculate your weight
              Remember                     weight = mass x gravity
Conclusion-
Where in the solar system would you weigh the most? How much would you weigh?
Where in the solar system would you weigh the least? How much would you weigh?
Trick Question
What would your mass be on the moon
What would your mass be on Pluto
Video review




        Watch the video and answer these questions


1)What objects equal roughly 1 Newton?
2)What is 1 Newton in Kgs?
3)What is the force of gravity measured in?
4)What is weight measured in?
5)How much does your mass change when you are on the moon?
6)Why do you weigh less on the moon? (refer to the mass of the moon)
Gravity and distance
The Force of gravity decreases the further you move the two masses apart

The further you move away from the Earth the smaller the gravitational pull
you will feel and your weight will go down.

                 Warning: THERE is gravity in space




                          Watch this video
                         On zero gravity on
                               Earth
When will there be no resultant force on the spaceship?




                                         Force
                                         From
                                         Moon
          Force from Earth




                                                   1/6 mass of Earth
Apollo 13
  1                                                                       5
                  2                3                 4




Imagine you are a member of Apollo 13 describe your journey with respect to the
gravitational pull of the Earth and moon.
