Calculating Weight on Various Planets

1. Calculating Weight on Various Planets Created Dr. A. Dávila

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

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

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

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

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

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

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

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

38. Weight on Jupiter y 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. Weight on Jupiter weight (lbs.) on Earth’s weight (lbs.) on Jupiter w x 2.5 90 90 x 2.5 225 Use a table to organize and calculate the data

40. Weight on Jupiter weight (lbs.) on Earth’s weight (lbs.) on Jupiter y-axis x-axis w x 2.5 90 90 x 2.5 225 100 100 x 2.5 250 110 110 x 2.5 275 120 120 x 2.5 300 130 130 x 2.5 325 140 140 x 2.5 350 150 150 x 2.5 375 160 160 x 2.5 400 170 170 x 2.5 425 90 225 Use another table to organize the data for the x- and y-axis.

41. Weight on Jupiter weight (lbs.) on Earth’s weight (lbs.) on Jupiter y-axis x-axis w x 2.5 90 90 x 2.5 225 100 100 x 2.5 250 110 110 x 2.5 275 120 120 x 2.5 300 130 130 x 2.5 325 140 140 x 2.5 350 150 150 x 2.5 375 160 160 x 2.5 400 170 170 x 2.5 425 90 225 100 250 110 275 120 300 130 325 140 350 150 375 160 400 170 425 Use this information to graph.

42. Weight on Jupiter y y-axis x-axis 90 225 Weight on Jupiter (lbs.) x Earth’s weight (lbs.) Graph each point.

43. Weight on Jupiter y y-axis x-axis 90 225 100 250 Weight on Jupiter (lbs.) x Earth’s weight (lbs.) Graph each point.

44. Weight on Jupiter y y-axis x-axis 90 225 100 250 110 275 120 300 130 325 140 350 150 375 160 400 170 425 Weight on Jupiter (lbs.) x Earth’s weight (lbs.) Graph all points or two points are enough to...

45. Weight on Jupiter y y-axis x-axis 90 225 100 250 110 275 120 300 130 325 140 350 150 375 160 400 170 425 Weight on Jupiter (lbs.) x Earth’s weight (lbs.) connect the points to form a continuos graph.

46. Weight on Jupiter y Weight on Jupiter (lbs.) x Earth’s weight (lbs.) Why is this type of graph helpful?

47. Weight on Jupiter y Weight on Jupiter (lbs.) x Earth’s weight (lbs.) If you want to include all types of individuals, what should the minimum value for the x-axis?

48. Weight on Jupiter y Weight on Jupiter (lbs.) x Earth’s weight (lbs.) Are the arrows on the line graph appropriate?
