Impulse Momentum

Lab Summary

Use a motion sensor and force sensor to explore the change in momentum that occurs in a collision, and how that change is related to the impulse associated with the collision.

Theory

This laboratory activity explores the change in momentum that occurs in a collision, and how that change is related to the impulse associated with the collision. This activity allows students to:

  • Calculate the change in momentum of a cart before and after a collision.
  • Study the relationship between force and time during the transfer of momentum associated with a collision.
  • Compare the change in momentum to the impulse associated with a collision.

Method

Students will gain experience conducting the following procedures:

  • Simulating an elastic collision with a cart, track, and force accessory bracket.
  • Measuring the change in velocity using a motion sensor and the force experienced by the cart during the collision using a force sensor.
  • Calculating momentum using the measured velocity of the cart.
  • Determining the impulse of a collision using the area under the graph of Force versus Time.
