Projectile Motion 3
Introduction: The initial velocity of a projectile can be broken into a component in the ydirection and a
component in the xdirection. On the other hand if the two components are known then
the initial velocity can be found b

Projectile Motion
Introduction: In studies of projectile motion students often question the reality of whether or not
horizontal and vertical motions are independent of each other. Students should recall
the demonstration of the two balls, one drop

You have probably watched a ball roll off a table and strike the floor. What determines where it
will land? Could you predict where it will land? In this experiment, you will roll a ball down a
ramp and determine the balls veloci
