Collect screenshots from the PHET projectile simulation that support your claims about the following:
7) Does mass affect the trajectory of a projectile? (make a claim and support it with evidence)
8) What angle gives the maximum range for a projectile - is it the same regardless of the mass and the initial velocity? (make a claim and support it with evidence)
Please include at least one screenshot from each group member as evidence for the above (so a group of four should have at least 8 total screenshots in their GROUP PROJECTILE DOCUMENT)
