Kevin Su Tuesday Experiment 9: Impulse and Change of Momentum Introduction In this experiment we found the relationship between the impulse imparted to an object and the change in its momentum. We use the Newtown’s second law of motion. Procedure 1.) Set up the air track, the force sensor and motion detector 2.) Set up the force sensor on the rod. Make sure the active part of the sensor lines up with the rubber band bumper on the air track cart. 3.) Place the motion detector on a rod stand and set it so that the sensing element is directed toward the track cart 4.) Use the balance, determine the mass of the air track cart 5.) Then click “ Collect” the logger Pro software 6.) Use five different kinds of masses on the cart with these procedures.

The air bag will save us because it creates less time of the impact and it changes the momentum which the book defines momentum is equal to impulse 2.) The impulses of both objects are equal because the definition of impulse is the change in momentum. 3.) The compact car has a small mass, which means the velocity, and acceleration will increase a lot. The large truck will be the opposite the mass is big but the velocity and accelerations will be smaller. Conclusion In this experiment we found the impulse and the change of momentum. We also measure the velocity of an object as it undergoes a collision. Also we measured the force that acts on the object during the collision and applied Newton’s second law....
