Momentum & Impulse

Lab Summary

Use a force sensor and a motion sensor to determine how the momentum and impulse associated with a collision are mathematically related.

Theory

Momentum and impulse associated with a collision are mathematically related.

  • Understand the forces and the distribution of forces associated with collision between a cart and barrier.
  • Experimentally unify the concepts of momentum and impulse.

  • Method

    Students gain experience conducting the following procedures:

    • Releasing a cart down an incline allowing it to strike a force sensor at the bottom of the incline.
    • Measuring the velocity just before and just after the collision.
    • Plotting a Force versus Time graph of the collision.
    • Comparing the change in momentum to the impulse.

    Sensors / Equipment Used:

    PASPORT Motion Sensor

    (PS-2103A)

    The PASPORT Motion Sensor accurately measures position, velocity, and acceleration of a target. Can be used to track the motion of carts, balls, people and more.

    PASPORT Force Sensor

    (PS-2104)

    Designed to measure both pulling and pushing forces. Uses range from collisions to tug-of-war.

    Base and Support Rod

    (ME-9355)

    The Large Base and Support Rod includes built-in leveling screws and an aluminum rod that is 12.7 mm (1/2 in.) in diameter and 45 cm long.

    Basic PAStrack Dynamics System

    (ME-6962)

    Two half-meter tracks designed to accept carts from the Dynamics Systems to study various motion related experiments.

    Track Rod Clamp

    (ME-9836)

    Fastens to the T-Slot of a Dynamics track and accepts a 1/2 inch rod.

    Discover Collision Bracket

    (ME-8973A)

    This bracket fastens to the T-Slot of a dynamics track and securely holds the Force Sensor for measuring collisions with a cart.

    Materials Used:

    Balance, 1200-g capacity
