As a continuation of the theme of potential and kinetic energy, this lesson introduces the concepts of momentum, elastic and inelastic collisions. Many sports and games, such as baseball and ping-pong, illustrate the ideas of momentum and collisions. Students explore these concepts by bouncing assorted balls on different surfaces and calculating the momentum for each ball.

Crunch! That is the sound that you hear when two cars crash into each other. This unnerving sound can be a good thing if it is the sound of a wonderful safety innovation developed by engineers, called the crumple zone. Mechanical engineers consider momentum and collisions when designing vehicles. A crumple zone is designed into motor vehicles to absorb the main impact of the energy being transferred during a crash, so the people inside don’t get hurt. Airbags are another engineering safety improvement to protect passengers from the impact of collisions. Calculate the momentum of a moving object. Recognize that momentum is proportional to mass and velocity.Know that momentum is conserved in an elastic collision.Understand that collisions and momentum play an important role in the design of safe automobiles. 50TeachEngineering.orgBailey JonesMatt LundbergChris YakackiMalinda Schaefer ZarskeDenise Carlsonhttp://memory.loc.gov/ammem/jrhtml/jr1947.htmlhttp://www.mcrel.org/whelmers/whelm22.asphttp://www.physicsclassroom.com/Class/momentum/momtoc.htmlhttp://www.iit.edu/~smile/ph8709.htmlhttp://www.exploratorium.eduS11417D8International_Technology_Education_Association-ITEA_STL_StandardsTechnologyE.
