Solving centripetal force problems on a vertical axis
Finish the classwork from today. Here is the link for the video on why astronauts float in space, even though they are so close to Earth.
1. In preparation for the orbit exhibition, read about the Universal Law of Gravitation. Try out the sample calculations at the bottom of the page and test your own understanding with the questions.
2. Scientific Notation worksheet (Click here for extra help)
1. Read about the physics behind roller coaster loops (and if you'd like, a tiny bit more + animation)
2. Wait, did Yenmin say if you experience too much Normal force, you can die? Yes, read about the g-force here.
3. Next week, we are going to examine satellites and planets in orbit. But they involve masses that are very, VERY big. Learn and practice how to write VERY big numbers (or very small!) in a more convenient notation than:
mearth = 5,972,000,000,000,000,000,000,000 kg (which is 5,972 with 21 zeroes behind it).
[If you're not sure how to solve the problems, take a look at the videos on the left side.]
I apologize for the delay! Unfortunately the video I made did not upload and we will have to do with an already-made video on youtube. Please take notes and try solving the practice problem along with the speaker in your notebook.
Circular Motion Problems
A brief overview of the roller coaster problem
Read about the Centrifugal Force and use it as a reference for WS 2.
Wonderwall assignment: due Thurs 2/11
Read about the Centripetal Force
(and if you dare, the...centrifugal force... Warning: Physics R-rated)
This website has interactives and "check your understanding" questions that can help you.
In your NB, write down key vocabulary, laws, concepts. Summarize each section in your own words.
