Students may ask how they can measure momentum in ten different types of collisions. Remind them that they can change the mass of each cart, change the speeds, and change whether the carts ‘bounce’ or ‘stick together’.


Sample Data


The screenshots show the Graph displays of velocity versus time for one collision.
