2. If you were on another planet, you would weigh differently than on the planet Earth.

3. Weight: the gravitational force exerted by the given amount of substance.

4. The weight that you feel depends on your actual mass.

5. The weight that you feel depends on your actual mass.
Mass: the amount of substance, the amount of material.

6. WEIGHT ON A PLANET
Weight on a planet depends on

7. WEIGHT ON A PLANET
Weight on a planet depends on
the amount of matter (mass) an object has,

8. WEIGHT ON A PLANET
Weight on a planet depends on
the amount of matter (mass) an object has,
the mass of the planet,

9. WEIGHT ON A PLANET
Weight on a planet depends on
the amount of matter (mass) an object has,
the mass of the planet,
and how far away the object is from the center of that planet.

10. All of the planets on our solar system have gravity.

11. Earth’s gravity is the force that pulls things down toward the center of the Earth.
All of the planets on our solar system have gravity.

12. This horizontal bar graph provides a visual representation of the gravitational pull levels on the planets.

13. Why does the gravitational pull vary?

14. Which planets have a greater gravitational pull than Earth?

15. Which planets have a greater gravitational pull than Earth?

16. Which planet has the greatest gravitational pull?

17. Which planet has the greatest gravitational pull? Jupiter

18. Jupiter’s gravitational pull is little more than
2.5 (2 1/2) times more than planet Earth

19. Jupiter’s gravitational pull is little more than
2.5 (2 1/2) times more than planet Earth
How does this information serve an individual preparing to visit the planet Jupiter?

20. Gravity effects weight.
How does this information serve an individual preparing to visit the planet Jupiter?

21. Gravitational pull is a significant factor on determining weight of an object.
How would you calculate your weight on Jupiter?

22. How would you calculate your weight on Jupiter?
____ my weight
How would you calculate your weight on Jupiter?

23. How would you calculate your weight on Jupiter?
____ my weight
Plus ____ my weight
How would you calculate your weight on Jupiter?

24. How would you calculate your weight on Jupiter?
____ my weight
Plus ____ my weight
Plus 1/2 of my weight
How would you calculate your weight on Jupiter?

25. How would you calculate your weight on Jupiter?
____ my weight
Plus ____ my weight
Plus 1/2 of my weight
Equals my weight at planet Jupiter
How would you calculate your weight on Jupiter?

26. My weight times 2.5
Equals my weight at planet Jupiter
Another method to calculate weight on Jupiter, is to use a formula.

27. 2.5 times my weight
equals my weight at planet Jupiter
Calculate weight at Jupiter.

28. 2.5 times my weight
equals my weight at planet Jupiter
w = my weight
j = Jupiter’s weight
Calculate weight at Jupiter.

29. 2.5 times my weight
equals my weight at planet Jupiter
w = my weight
j = Jupiter’s weight
w x 2.5 = j
Calculate weight at Jupiter.

30. Create a graph so others can have an idea of how much they will weight at Jupiter.

31. Weight on Jupiter
x-axis
The x-axis begins with 90 pounds because an average adult weights about this much or more.

32. The y-axis begins with 200 pounds because 90 x 2.5 will equal 225.
Weight on Jupiter
y-axis
The y-axis begins with 200 pounds because 90 x 2.5 will equal 225.

33. The y-axis begins with 200 pounds because 90 x 2.5 will equal 225.
Weight on Jupiter y
Weight on
Jupiter (lbs) x
Earth’s weight (lbs)
The y-axis begins with 200 pounds because 90 x 2.5 will equal 225.

34. Use a formula to calculate the weights.
Weight on Jupiter y
Weight on
Jupiter (lbs) x
Earth’s weight (lbs)
Use a formula to calculate the weights.

35. Weight on Jupiter Weight =90 Weight on Jupiter (lbs)y
Weight =90
Weight on
Jupiter (lbs) x
Earth’s weight (lbs)

36. Weight on Jupiter Weight =90 w x 2.5 = j formula Weight ony
Weight =90
formula
w x 2.5 = j
Weight on
Jupiter (lbs) x
Earth’s weight (lbs)

37. Weight on Jupiter Weight =90 w x 2.5 = j 90x2.5 = j substitutey
Weight =90
substitute
w x 2.5 = j
90x2.5 = j
Weight on
Jupiter (lbs) x
Earth’s weight (lbs)

38. Weight on Jupiter Weight =90 w x 2.5 = j 90x2.5 = j 225 = jy
Weight =90
solve
w x 2.5 = j
90x2.5 = j
225 = j
Jupiter’s wt.
Is 225 lbs.
Weight on
Jupiter (lbs.) x
Earth’s weight (lbs.)

39. Use a table to organize and calculate the data
