  • This version of the Ballistics Pendulum is for those who already have a PASCO Projectile Launcher.

    Features

    Repeatable: The three velocity settings on the Projectile Launcher produce consistent velocities.

    Accuracy: The 0-80° angle measurement scale resolves to 1/2°, leading to experimental results within 2.5% of predicted values.

    Compact Storage: Four units can be stored in the same space as one older-style ballistic pendulum.

    Removable Pendulum: Remove the pendulum to determine its mass and center of mass. It can swing freely so students can determine its rotational inertia. Mount the pendulum backwards so the ball bounces away for elastic collision experiments.

    Vary Ball and Pendulum Mass: Two 50 g masses can be added to the pendulum, and two steel and two plastic balls are included.

    Projectile Launcher: Mount the Projectile Launcher on the other side of the base, and students have access to all the accessories that come with the Short Range Projectile Launcher (ME-6800).

    Unique Angle Measurement: The PASCO Ballistic Pendulum pushes a low friction, low mass pointer to the highest point. It remains there, permitting an accurate measurement.

    Add Masses: Two 50 g masses can be added to the pendulum, and two steel and two plastic balls are included.

    Demo: Elastic/Inelastic Collisions

    How It Works

    A projectile is fired into a pendulum, causing it to rise.

    Using the projectile mass, the pendulum mass and the rise in pendulum height, students can calculate the gravitational potential energy of the system.

    Since the potential energy is equal to the pendulum’s kinetic energy at the lowest point, students can calculate the speed of the pendulum at impact.

    Applying the Law of Conservation of Momentum, the projectile’s speed is easily calculated.
