17. What is terminal velocity?___________________
18. Why does terminal velocity occur?________________
19. What would happen if terminal velocity did not occur? (Think about hailstorms, skydiving, etc..
.)

Answer the questions within the site above within the page.
Go to “Fear of Physics”. Read the instructions and drop the ball from the top of the Empire State
Building. Click on “show the ball’s trail”, then click “go”. Answer the next three questions. (21-23)
Fear of Physics (http://www.fearofphysics.com/Fall/fall.html)
21. Write down how fast gravity accelerates objects.
22. When will the ball hit the ground if dropped from 443 meters up?
23. How fast in miles per hour will the ball be traveling when it hits the ground?

24. Why do feathers fall so slowly?
25. What happens when the moon moves by us?
26. The moon should be traveling in a straight line, but it doesn’t. Why is that?
Go to the next site and enter your weight.

30. What is your weight on the sun?
31. What is your weight Pluto?
32. What is going on with mass and weight?
33. What’s the relationship between gravity, mass, and distance?
Go to this site
(http://www.classzone.com/books/ml_science_share/vis_sim/mfm05_pg79_vacuum/mfm05_pg79_vac
uum.htmland) watch the video. See what happens when a hammer and a feather are dropped at the
same time on the moon.
34. What does the astronaut say about it?
Directions: Go to the following websites and answer the questions about gravity. Go to the following
website: http://helios.gsfc.nasa.gov/qa_gp_gr.html
Answer these questions:
35. What is a “G”? How fast does it travel (In meters per second squared)?
36. What is the speed of gravity?
37. What causes gravity on earth?
38. According to Einstein’s Theory of General Relativity, what is gravity?
39. What happens to gravity as mass increases?
Next go to this website:
http://teacher.scholastic.com/activities/explorations/space/level1/MoonOlympics.htm. Complete the
Moon Olympics and explain the difference that each sport or “event” would have on the Moon
compared with Earth. (There are five events.)
40. Weightlifting:
41. Diving:
42. Golf:
43. Skateboard Half-Pipe:
44. Parachuting:

Go to the following website:
http://www.pbs.org/wgbh/nova/galileo/experiments.html. Click on the link that says Galileo’s
Experiments (in the center of the webpage, the font is small) and answer the following questions about
Falling Objects.
45. What will happen when she drops the two cannonballs of different masses?
46. Was your prediction above correct? If not, what did happen?
47. Read the explanation as to why the two cannonballs of different masses drop the way they do.
Summarize it in 1-2 sentences below.
Now click on the projectiles simulation. Answer the following questions:
48. What will happen when she drops one of the cannonballs and pushess the other one away from
the tower?
49. Was your predicton above correct? If no, what did happen?
50. Read the explanation as to why the two cannonballs that were dropped differently drop the
way they do. Summarize it in 1-2 sentences below.
