GL141 - The monkey and hunter experiment using a video camera
The monkey and hunter experiment is a useful demonstration of projectile motion, specifically the independence of horizontal and vertical velocities. It is typically demonstrated at AS Level, but a discussion of it could be had with more able GCSE students, and it remains a popular experiment to show on Open Evenings. This particular version of the experiment uses a Stomp rocket, which is much larger than the traditional ball bearing. This means the experiment can be recorded, and played back to show clearly the parabolic path of the rocket, and the vertical displacements of both the rocket and monkey being the same.
