 * Mythbusters & The Scientific Method **

=1. Explain the myth that you wish to investigate:= We plan to investigate the myth that it is possible for a car to jump over a bridge, broken at different angles, which happens in many movies.

=2. What is your prediction and why do you believe this?= We believe that it is possible as long as the velocity of the car is great enough and that the angle of the bridge is correct.

=3. What are the main physics concepts you will be considering (e.g. Inertia, Newton's 3rd Law, conservation of Momentum, etc.)= Conservation of Energy, Forces, momentum,

=4.What are the variables that you will be measuring in your experiment? What are the controls in your experimental setup= . (A control could be that you have to wear rubber gloves so that you don't sweat on your equipment) = Controls = · car size, weight · d of ramp, road, gap · friction of surfaces · angle of inclination · speed of car

=Variables=


 * angle of inclination (when speed is controlled)
 * speed of car (when angle of inclination is controlled)

=5. Describe your experiment in point form= Steps of the experiment: > > =6. How do you think you will analyze and present your data (types of charts, graphs, pictures, etc.)=
 * Place toy car on a specific point on the ramp.
 * Activate motion sensor, then allow car to roll down the ramp and progress to the second ramp.
 * The car either makes the jump or lands short, and we record results and adjust accordingly.
 * Our different experiments will include different ramp angles along with various speeds.

We will analyze our data using an array if equations. Firstly we will calculate gravitational potential and kinetic motion as well as the final velocity as the car hits our "bridge". We will also have to account for the friction encountered by the car while traveling on the various surfaces. With that information we can then adjust where we drop our car from, along with the angle of the bridge. Our data will be presented primarily through the use of graphs and charts to present the data, which will mostly consist of different velocities, friction, gravitational potential and kinetic motion. Our final product will consist of a sample movie clip where a car jumps over a broken bridge as well as our experiments and oral explinations.

COMMENTS;

Nice, simple experiment. You should be able to get some good results. You should do multiple trials at each angle/velocity so that you can do a %variation calculation. This will allow you to demostrate the precision of you experiment.
