Introduction
A flywheel is a large rotating disc acting as a mechanical collection of kinetic energy. A flywheel is resembles a mechanical battery in the way it stores kinetic energy. With comparison to chemical batteries, flywheels have a vastly greater life span. Increasing the speed of the rotation of the flywheel will increase the energy it stores.
Flywheels rotate with a connecting rod; this is known as a shaft. The shaft is where energy moves in and out of the flywheel. This experiment is undertaken to show the actual time measured for a mass, connected to a flywheel with a piece of string, to travel a distance h is equal to the calculated time of the same height.
An example of flywheel applications is the replacement of substations in railway systems with flywheel systems. The number of passenger on trains are increasing, increase the weight load on the train, the spacing between trains decreases and voltage drops are becoming more common on rail systems. Substations can be upgraded to add power conditioning equipment, space constraints and difficulty of increasing power distribution can make it very costly to upgrade some substations. Another solution is to install flywheels to increase voltage output. The flywheel systems can be located in places where the voltage output is
