11. Weight Why is a person’s weight different on the moon/Jupiter???
The moon exerts much less gravitational force on you!

12. Compare to Jupiter
Jupiter exerts a much greater force on you!

13. Weight Why is the pull of gravity different?
Your weight is a measure of the pull of gravity between you and the planet you are standing on.
This force of gravity depends on mass of the planet you are standing on.
Massive planet (great mass)---- the greater the gravitational pull  the more you weigh
Small planet (small mass) – there will be less gravitational pull on you  you weigh less.

14. Mass Answer this question…..

Mass is different than weight!!!!!
Mass is the amount of matter (stuff) in an object
If you were to travel to the moon or to Jupiter, your mass would not change.

1. A lot of people think mass and weight mean the same thing, but they do not. How are they different?
2. Explain your answer by explaining what happens to your weight if you were to go to another planet or the moon.

16. Units of Measurement Mass vs Weight
To measure matter, scientists use the International System of Units (SI units)
Mass --- grams/kilograms
Weigh - Newtons

17. Prefixes are used in front of units of measurement
Grams – unit of measurement for mass
“Kilo” – means 1,000
So 1 kilogram = 1,000 grams
“Milli” = 1/1000th or 0.001
What does 1 milligram mean?
