Investigate the fundamentals of the equilibrium with this simple moments of force apparatus. A centrally mounted beam represents a two-arm lever. Movable riders are placed on the lever and weights are applied. Equilibrium is attained by moving the weights. Distances from the pivot point can be read from an integrated scale. The calculation of the lever arms is verified in the experiment. Includes instructions.
SKU: PH10586Monkey & Hunter
This apparatus illustrates the effect of gravity on the projectile motion. An elastic powered gun is supported from a battery operated small electromagnet. It fires ping pong bullet balls at a model monkey. When the projectile is fired, the electromagnetic circuit breaks. The trajectory is easily visible. Both monkey and bullet fall at the same rate and the bullet always hits the monkey regardless of how far away the monkey is. This proves that the horizontal and vertical motions are independent of each other. This unit includes a table clamp mounting plate and it may also be used as a trajectory apparatus. Requires support stand and low voltage battery, which is not provided with the apparatus
