Metal car lab

In Physical science this week we did a lab that has to do with force, acceleration, and mass. We were given a metal car and a set of weights spanning from 5g to 1000g. We then set up a wood runway for the metal care to go down. Each time we made the metal car go down the ramp, we would time it, and each time we would put a heavier weight. We used a back pack to make the slope a slant and we used a binder to make the car stop. I really enjoyed this lab, I think it was a fun way to see how weight may affect a car on a hill and it gives me a better understanding of what weight really does.
