This HTML5 app shows the motion of a projectile.
The "Reset" button brings the projectile to its initial position. You can start or stop and continue the simulation with the other button. If you choose the option "Slow motion", the movement will be ten times slower. You can vary (within certain limits) the values of initial height, initial speed, angle of inclination, mass and gravitational acceleration. The radio buttons give the possibility to select one of five physical sizes.
The effect of air resistance is neglected.
