Experiment 4 Inelastic Collisions‚ Conservation of Momentum and Non Conservation of Kinetic Energy Preparation Prepare for this week’s experiment by studying Newton’s Laws‚ linear momentum‚ and kinetic energy. Principles In this experiment you will study a collision where a moving object strikes and sticks to an initially motionless object. When the colliding objects stick together the collision is said to be completely inelastic. The net momentum of the system should not change‚ but the

concentration levels. For this experiment we will also be using a catalyst to speed up the production of oxygen gas. The catalyst being used will be iodide ions‚ which will be introduced into the actual reaction through a mixture of potassium iodide‚ KI. Once all the reactions are complete the rate will be found by using the rate law‚ which shows the dependence of the rate of the reaction of both the iodine and the hydrogen peroxide. Procedure For this experiment we had to work in pairs.
