Physics. We did this thing with a motion sensor and see how the speed changes with steeper slopes. The steeper the slope, the faster the car goes. Why?? Gravity?? Plz explain.

Gravity draws an object towards its strongest point. The main things holding you back are air resistance and friction. As a hill gets steeper, you are more in line with the center of gravity, so it overcomes friction and you move faster. Eventually when you are moving vertically there is no friction other than air resistance itself. At this time you will accelerate at 32 feet per second every second until you either hit something or reach terminal velocity which is around 120 mph. Air resistance (on the Earth at least) will not allow you to travel any faster.

well, you can use x and y vectors for this (x = horizontal movement, y = gravity). When the slope is steeper, the y vector is longer than the x vector. As a result, gravity will have more of an effect on a steeper slope than on a less steeper slope due to gravity having less of an impact on the movement of the object.

First its because of gravity, the fact that it pulls object towards the earth. Second is the friction. I think t force of gravity is stronger than the force of friction on steeper slopes. Unless the surface of the slope is a negative magnet and your tire is positive it well not fall down. Joke! And lastly, is the pressure (the air pressure).

Things go downhill faster on steeper slopes because there is less friction holding the object back.

Where should I start? First of all, that is not a hypothesis, that is a question. A hypothesis is a statement. Second, the instrument you use is THE PLANK. Third, this is the dumbest project I've ever heard of. Fourth, you're cheating on the dumbest, simplest project ever. Fifth, I will not even TRY to correct all those horrendous grammatical errors in the sentence. All in all, you're an idiot. Feel free to go back to second grade sometime soon.

Because of Gravity of course...
and it goes faster if there is less friction and stuff

gravity. it pulls it down to the center of the earth

when object goes off hill, where on the hill does it go fastest, below the top, middle way or down at the bottom of hill?

ya gravity pulls it down so therefore, it goes faster. :D
