Energy Conservation PHY133 - Classical Physics I Laboratory Conservation of Energy In this week's lab, we will study the vector nature of force and energy conservation using a glider on an air track. A vector can be expressed as the sum of its components along a conveniently chosen coordinate system. In the first part of this experiment, we will study the component of the gravitational force, mg sin ? , by using a tilted air track, where ? is the tilt angle. For an isolated system, the total energy must be conserved. In the second part of the experiment, we will examine the law of energy conservation by observing the transfer of gravitational potential energy to kinetic energy. Equipment 1 air track glider with photogate 1 light sensor 1 interface box 1 computer with timing program 2 wood blocks 10 and 20 gram weights recording tape Method A battery-powered photogate is mounted on the glider. When activated with the small push button on the side of the glider, the photogate turns on a bright, light emitting diode (LED) whenever the picket fence over the air track blocks the photogate. A light sensor at the end of the air track receives the LED signals and timing program in the computer measures and records the time intervals between successive lightings of the LED. In the first part of the experiment, releasing the glider from rest on a tilted air track, the acceleration, a, of the glider can be measured and the component of gravitational force, mg sin? , along the air track
