Physics 211 Momentum Pre-lab
Name: _______________________________________ #___________
In the experiment you will analyze several 1-D collisions to see whether momentum and/or kinetic energy
are conserved. We'll analyze three simulated collisions here using the same methods.
. Note that momentum is a vector. Take “to the right” as the positive
Impulse is the change in momentum.

(1) Start with an
. Adjust the orange mass to 1 kg, and the blue mass to 3 kg. Make Orange’s
initial velocity 2 m/s, and Blue’s initial velocity 0 m/s.
Run the simulation and stop it after the carts collide.
Record the final velocities (pay attention to the +/- signs) in the table.
(2) Reset the simulation and run it again as an
. Record the final velocities in the table.
