Trajectory of a projectile

Classical mechanics index

The trajectory of a perfect projectile (over a flat surface, ignoring air resistance) describes a parabola.

In reality, air resistance makes thrown objects fall much closer that expected by this calculation suggests. Other models can take this into account, but need information about the object thrown.
This calc allows you to change the strength of gravity, so you can see how the trajectory would appear e.g. on the moon, or on another planet. For Earth, set gravity to 1 g (or 9.80665 m/s²).
