The purpose of this lab was to discern the different ranges of a projectile fired at
different, complementary angles. With these said measurements, the relationship between the
angle fired and the distance traveled had to then be determined. To accomplish

Purpose:
The purpose of this experiment is to observe the results of launching projectiles at
complementary angles
Materials:
The materials required for this lab are a marble launcher, marble, sand, tray, plastic cup,
measuring tape, safety goggles, and r
B. The object starts off with a distance of zero units relative to the origin. As time increases,
the distance from the object to the origin gradually increases with a constant, positive
velocity. For a very short time, the object appears to be at rest wi
For both graphs, the independent variable was time (in seconds) because the value of the
other variables did not affect it. Since average velocity was affected by time in the first graph, it
was the dependent variable. Since total displacement was affecte

It was predicted that the measured angle for the brick wrapped in sandpaper will be
higher than for the brick left unwrapped. Because there is more friction between the
