SCENARIO 3: 100% Elastic collision between balls of unequal mass moving towards each other DIRECTIONS: STEP 1: Make sure the elasticity is still set at 100% and make the mass of the red ball different from the mass of the green ball . Select an easy whole number initial velocity for both balls making the velocity of the red ball positive and that of the green ball negative. 1. Predict what will happen after the red ball hits the green ball by scribbling out the wrong answer choices in each answer grouping (EX: slower same(faster) After the collision, the red ball will move backwards/forwards at a speed that is slower/same/faster than its original speed. The green ball will move backwards/forwards at a speed that is slower/same/faster than the its initial speed. The speeds of the two balls after the collision will be the same/different. 2. Run the simulation and see what happens. Were you right or wrong? Right 0 Wrong STEP 2: Rerun the simulation. Fill in the data table below with the mass, velocity, and momentum BEFORE and AFTER the collision. Remember: the mass of the red and green balls should be the same and their initial velocities equal and opposite Before Collision After Collision Velocity Momentum Velocity Momentum Ball Mass (kg ) (m /s) (kg *m /s) (m/s) (kg *m /s) 1 Total (Add Column values What do you notice about the total momentum before and after the collision? What is the trend with the momentums before and after? MULTIPLE CHOICE. When something happens over and over again without exception, in science it is a: A. Hypothesis B. Law C. Theory D. Fact EUREKA! You just discoverd the (Ans.to MC Question) of Conservation of which states that momentum is conserved before and after a collision
