Homework Help: Physics Gravity Car Research Help

  1. May 10, 2009 #1
    I know I am abandoning the template but my question doesn't really fit in that template so sorry.

    Anyway for my Physics Assignment I have to do an EEI on a gravity car that I have to build, see this image for more help: http://seniorphysics.com/physics/gravity_car.jpg. Anyway I am struggling at the research bit. I have no idea what to research.

    What should I be researching, what should I be looking for in research and where should I be researching(eg Google or library etc)?

    I have tried 'physics of "gravity car" -anti -zero' in Google with no such luck. I just need some guidance.

    Thanks in advance.

    Do you understand these concepts?

    gravitational potential energy
    kinetic energy
    mechanical friction
    air resistance

    Then you should be able to work out why the car will start, accelerate, slow down, and stop.

    For a start you are thinking of the entirely wrong thing if you are putting anti or zero gravity into google.

    How is the car driven in that picture do you think? (hint look at what is attached to what)

    No I put don't include. (-) means don't include.

    Fair enough, it would have been less confusing to just not put anything rather then saying what you didnt look at as then we would know you were on the right track. :P

    But anyway...

    How do you think the car works in the picture?

    Is the car supposed to go a long distance? Maximum velocity? Drag race?
