Lab 7

Lab 7 LINK http://phet.colorado.edu/en/simulation/energy-skate-park Lab 7: Energy Introduction and Objectives The modern energy concept was introduced in the early part of the 19th Century (ca. 1802 – 1807) as a means of extending physics without the need for the cumbersome vector calculations that characterized Newton’s mechanics. This lab will explore how energy flows back and forth between the potential and kinetic energies as objects move along a sloped track. When the student has completed this lab they should be able to: Understand the nature of potential and kinetic energies. Be able to calculate the total energy of a system Be able to predict motion based on conservation of energy.
