The energy would have went to heat, going to sound or thermal energy.

The bigger the wheel, the farther it would go. The smaller wheels, the smallest it would go. The axle had to be small but also able to move so the wheels weren't moving but the axl was.

Calculating work you would have to use w=fd (work= force times distance

Our car went at a slow but constant speed, which resulted in it going far.

How high up the ramp would your car go?

It probably would not go very high up a ramp. It doesn't have enough power to go up the ramp.

by using records, which helped with the overall function of our car. Also, we made sure that both sides of the car were even.

By using records instead of cd's, because they have better traction. Because we used records, we did not need to use tape or anything- the records have thicker sides that help them stayin place better.

we tightened the bolts/screws to make sure the wheels would not wobble, or move. We also added spacers onto the axles so that everything would stay in place.

If the average force needed to set the spring was 5.0 N, and the circumference of 1/2 of a turn of the mousetrap was 0.14 m, how much work did you do?

w=fxd. We would multiply force and distance to find the amount of work done on the car.
