Description
In this simulation you can look at the paths of four projectiles, all shot over level ground. The projectiles are launched at four different angles, 20 degrees, 30 degrees, 45 degrees and 60 degrees. You can choose whether you want them all to have the same horizontal range, the same maximum height, or the same initial velocity. Their initial velocities will be automatically adjusted based on your choice. For each scenario (same range / same max. height / same initial speed) you should be able to answer questions such as:

Which has the greatest initial horizontal velocity?
Which has the greatest initial vertical velocity?
Which has the greatest initial speed?
Which has the least initial horizontal velocity?
Which has the least initial vertical velocity?
Which has the least initial speed?
Which has the greatest time in the air?
Which has the least time in the air?
