JHS AP Physics Classes Study Energy Properties

Jamestown High School students Johnna Graham and Ryan Salemme work with AP physics teacher Steve Propheter to determine the minimum height at which an object needs to be released to just barely make it around a loop-the-loop. Students measured and used the concepts of energy, forces and centripetal motion to determine where to release the object. If they incorrectly determined the release point, they then had to determine their percent error and figure out what caused the error. The AP physics class relates this topic to amusement park engineering, highway design and Olympic events to give real-life examples of energy and conservation.
