Hi,
I am currently thinking of a topic for my science fair project, and I was thinking about calculating the effect of gravity between two masses. The first mass(most likely lead or some other dense material) will be taped/glued to an bar with minimal mass, such as styrofoam or thin plastic so it will have minimal effect on the result. The bar will then be suspended from the roof of an box with a string. Then two pieces of lead far bigger than the ones suspended will be placed at the same height at a specific distance from the bar.
Theoretically, the x-forces and the y-forces are two different forces, and they don't affect each other, so Earth's gravity shouldn't affect this experiment at all. To remove the constant motion caused after the initial gravitational force, a dampener will be placed, which will most likely be a pad dipped in water to dampen the motion so only gravity affects it.
The independent variables will most likely be the density of the two masses, the ratio of the two masses, and the distance between the masses. The dependent variables will be the speed the first mass moves.
I would like to know if 1. if this is even possible, 2. if i should change some features to make it more interesting, and 3. If this overall would be a good experiment and is it original. i must do a project which is new and has not been done before.
