    Physics of "Interstellar"

    In TV & Movie Physics

    Posted

    Physics of “Interstellar”

    After watching the movie “Interstellar,” your assignment is to pick two different story / plot points or phenomena demonstrated in the film and analyze the physics involved. Is what they demonstrate consistent with current theories? Why or why not?

    Post your findings in the APlusPhysics Community, Forums section, under TV & Movie Physics by responding to the Interstellar thread. You can create two separate responses, one for each topic, or combine them into a single post. Respond to the posts of at least two other students.

    here some more information for those of you that are really interested in what's happening and how it works what I am doing in polyphonic overtone singing ;)

    (......and, YES, YOU CAN LEARN THAT!!! I wasn't born with the skills of polyphonic overtone singing....)

    AP Physics 2 Essentials - An APlusPhysics Guide

    AP Physics 2 Essentials is an easy-to-read companion to the AP Physics 2 curriculum, featuring more than 450 worked-out problems with full solutions. AP Physics 2 Essentials covers all major topics of the AP Physics 2 course, including fluids, thermal physics, electrostatics, circuits, magnetism, optics, and modern physics.

    AP Physics 2 Essentials is integrated with the APlusPhysics.com website, which includes online question and answer forums, videos, animations, and supplemental problems to help you master the essential concepts of physics.

    This book is designed to assist physics students in their high school AP Physics courses both as a guide throughout the course as well as a review book to assist in end-of-course exam preparation. Its focus is on providing the bare bones, essential concepts necessary for success in the course in a straightforward and easy-to-read manner, leaving development of in-depth problem solving and lab work to the classroom, where it is most effective. In short, this is not intended as a substitute for a standard textbook or course, but rather as an invaluable supplementary resource.

    This book includes more than 60 AP-style problems to test your understanding and help prepare you for the AP Physics 2 Exam. Additional supplemental problems are available on the APlusPhysics website.

    AP Physics 2 Essentials Proofreaders Sought

    In Announcements

    Posted

    After more than two years in development, the AP Physics 2 Essentials review book is moving into its final stages. Rough drafts are almost complete, chapters are under review by our grammatical editor, and preliminary layout / design is underway. So what's left? The team and I have a chapter to finish, two chapters to tweak, indexing, and the appendix to finish.

     
    Volunteers are being sought to examine chapters of the book and look for technical errors / opportunities for improvement before the book goes into the final proofing stages. If you're a certified physics instructor and willing to read a chapter, verify the problems / solutions, etc., we'd love your help! Those providing feedback will be given a free PDF license for the completed book (e-reader version, unfortunately not printable due to licensing restrictions), and of course, inclusion in the credits.
     
    If interested, please send an e-mail to info@aplusphysics.com and I'll be in touch! Thanks so much for the ongoing support, and make it a great 2015! -- Dan Fullerton

    This was an extra credit project for my Exploration of Space course Spring 2009. One of my more creative endeavors:-D

    Keplers Laws All Three

    A natral orbits controlled by gravity

    Celestial Bodies all follow, follow one.

    Spaceships with their engines off, orbit in one too

    Keplers Laws explain them and theres only 3 to know

    Orbits arent circles

    The planets move in ellipses you see

    Suddenly I see (Suddenly I see)

    Pariapsis is close to gravity

    Suddenly I see (Suddenly I see)

    Apopapsis is farthest from gravity

    Suddenly I see (Suddenly I see)

    For earth close is perigee

    Suddenly I see (Suddenly I see)

    The farthest from the Earth is apogee

    The first law talks about the orbits shape

    If its bound its elliptical, elliptical.

    Theres 2 foci with the occupied

    The major axis is the largest diameter of it

    Unbound orbits

    Are called hyperbolic in shape

    Suddenly I see (Suddenly I see)

    Round means low eccentricity

    Suddenly I see (Suddenly I see)

    Our planets make orbits like these

    Suddenly I see (Suddenly I see)

    Stretched is high eccentricity

    Suddenly I see (Suddenly I see)

    Astroids and comets are like these

    [

    And the second law is

    At the pariapsis and slowest at apoapsis

    The third law talks about the period

    The time to make an orbit

    The bigger the major axis the longer the period

    The bigger the major axis the greater total energy

    Periapsis has the greatest energy of motion

    Apoapsis has the greatest energy of position

    Total Energys the same at any point in orbit

    Suddenly I see (Suddenly I see)

    Total Energys the sum

    Suddenly I see (Suddenly I see)

    Of energy of motion and position

    Suddenly I see (Suddenly I see)

    The sum is constant

    Suddenly I see (Suddenly I see)

    Because of conservation of energy

    Suddenly I see (Suddenly I see)

    Bound orbits have negative total energy

    Suddenly I see (Suddenly I see)

    Unbound have positive total energy

    Suddenly I see (Suddenly I see)

    These are Keplers Laws all three

    Suddenly I see (Suddenly I see)

    They explain the solar system cant you see.

    Accelaration

    In Labs and Projects

    Posted

    True, but you weren't accelerating downward.  Your weight (the force of gravity on your car) was mg, where g was 9.81 m/s2, but you weren't accelerating vertically.  (PS -- not quite a blog post for the class -- see me to talk about where to put them).
