Monkey And Hunter
To demonstrate the independence of horizontal and vertical components of motion in a dramatic way.
Monkey and hunter assembly, as photographed.
Various gun angles and projectile velocities may be used.
The "gun" is aimed at the monkey and shot. As the projectile leaves the muzzle of the gun it breaks a circuit producing the magnetic field which holds the monkey in place. The monkey then begins to fall at the same time the projectile is fired directly at the monkey. Due to independence of horizontal and vertical components of motion, the projectile will strike the monkey.
