To demonstrate the laws of conservation of momentum and trajectory. Features a nylon block pendulum with tapered rubber insert, leveling and adjusting screws on both pendulum and base, and a rubber bumper to prevent damage on impact. Unit contains a scale marked in degrees for recording the height and is registered by a counter-weighted needle that remains in place at the height of the pendulum arc. With instructions.
Features
Purpose: It is used in physics education to demonstrate the conservation of momentum and energy in a perfectly inelastic collision. Components: It typically consists of a launcher (often a spring-loaded cannon) and a pendulum with a block that catches the projectile. Measurements: The device has a graduated scale, often marked in degrees, to measure the maximum height or angle the pendulum swings after catching the projectile. A counter-weighted needle or marker may be used to register the height of the arc. Adjustability: The pendulum and base may have leveling and adjusting screws to ensure proper setup. Use: By measuring the mass of the projectile and the pendulum, as well as the maximum height of the swing, one can calculate the initial velocity of the projectile.
