Marble Motion


Today in science class we did a lab to see dose the mass of a marble affect how it moves. One question n that we had was when given a force what happens to it motion. We tested this lab by taking different kind of balls to see how they move when force is applied. When we applied we used straw and blew through them to make force. First we used the light weight balls to see how they move most of them just came across the table easily and didn't make any curves because they were going quick. Then we came to the bigger balls. The tennis ball was too heavy and we couldn’t move it. The Styrofoam balls were big but they didn’t much density so they were easy to my. So the mass of the marble dose affect its movement because the more mass the more force has to be applied. I would like for us to see which marble will accelerate the fastest when going down a ramp.
