Projectile Motion Experiment

Item Code: SK088

Principle and Working:

The projectile motion is for experimentally determining trajectories when a projectile is launched either horizontally or at an angle. Angles between 0° and 90° may be selected. Varying the tension in the spring can also enable different launch velocities.




  • Continuously variable projection angle between 0° and 90
  • Variable Launch Speed: For short range or longer range experiments.
  • Flexible Launch Positions: Stable stand offers horizontal and variable angle launching positions.
  • Unique Piston Design: Minimizes projectile spin to ensure repeatability of impact position.
  • Pair of photogates for velocity measurement.

  • To determine the range of projectile as a function of the angle of inclination.
  • To determine the (maximum) range as a function of the initial velocity.
