Projectile motion is motion involving only the force of gravity. Since gravity is constant, and constant forces cause constant acceleration, the graph of position vs time for the marble would be a parabola.dxu46 wrote:Doesn't projectile motion involve a curve?

Re: Experimental Design B/C
I think that dxu46 can go. We should all review the various types of experiments. I would caution you that rolling motion versus projectile motion will come up in competition.UTF-8 U+6211 U+662F wrote:Projectile motion is motion involving only the force of gravity.

A proper analysis must discuss and interpret all data, commenting on outliers and accurately explaining and interpreting trends in the data using detail and supporting evidence.dxu46 wrote:What needs to be included in a proper Analysis?

How many levels of IV have to be ID'd?
How many CV's have to be ID'd?
1. at least 3
2. at least 4
