You can adjust the angle of the cannon relative to the horizontal. The muzzle velocity can also be adjusted. A cursor is provided to enable the making of measurements. The “Theory” button provides a mathematical representation of the experiment. Air resistance is ignored.

Click and tilt the cannon.

Click on to shoot and to stop the motion.

Click on 'theory' to show a mathematical representation of the experiment.

Learning goals

  • To illustrate a parabolic free fall experiment.
  • To show the independence between horizontal and vertical components of motion.
  • To see the effects of the muzzle velocity and the initial angle on the path of the cannon ball.
