Work-Energy Theorem

This lab is similar to Lab 5 in that it uses an inclined air-track and a glider moving down the air-track. One uses the work-energy theorem to calculate the velocity of the glider after it travels a measured distance down the air-track, by having measured the work done on the glider as it moves down the air-track. A photogate system is used to measure the velocity. Students measure the velocity five times and then obtain the mean and standard deviation of the mean for their experimental velocities. This is then compared to the theoretical result obtained using the work-energy theorem.
