The Path of an Marble

Hello guys, in science class lately we have been measuring the path of an marble. We {my partner and I}did this by putting tape on one side and labeling it start and then at the end of the table we would put another label which will say finish. Then we took the materials which were for us



Our guiding question was does the speed of the marble depend on the mass?

My answer was that it does because if the marble/ball has a lot of mass then it would be very difficult for it to start which equals an disturbance in the speed.


Materials

• Metal Marble
• Little Marble
• Big Marble 
• Tennis Ball 
• Golf Ball {worst of all}
• Straw 

When we got all the tools necessary we would take the straw but it next to the ball and blow on it with a steady breath. We would continue doing this for all of our materials. Of course because of the size and mass of the marbles/balls some of them didn't have enough density to go as fast or start {like the golf ball} So our teacher told us to draw all of the marbles paths. And  by my analyzes non of the marbles/balls would go straight. They would all curve or stop depending on there mass.
