First things first, you need to draw a design of the race car that you think will work great.
This is the design that Keanna and I built for our race car.
Some things that you might need to get you started will be nails, power saw, wheels, wire, perfectly a skinny string of some sort, a drill, a sharpie, a piece of wood about 1 foot and a tape measure.
Draw out what you're going to cut.
Draw out the front of the race car.
Cut out the pieces that you drew.
Draw out one continuously hole through the two back rectangles, then when you are done drawing you can move on to cutting it out.
When that's all done stick a little pipe that will stay in the hole, you drilled and make sure there's something right in between
Take the coat hanger and bend it into a "U" shape then connect it to the mouse trap, right by the spring, closest to each other.
This is how it will look when your finished but not painted.
If you want, you can paint the car.
Acceleration: when we let go of the coat hanger, that's connected tot he mouse traps, then the racer accels as it goes.
1st law: the racer doesn't move unless we let go of the hanger and it stays in motion until something hits it.
2nd law: If our racer had more mass, it wouldn't have much acceleration.
3rd law: the wheels push back on the ground and the car goes forward pushing an equal and opposite force.
