Abstract
A commercial didactic experiment is used to investigate the free fall of a metallic ball. The equipment is composed by five photosensors (is a timing device used for very precise measurements of high-speed or short-duration events) that allows to measure four intervals of time after the electromagnet releases the metallic ball. The experimental setup is explained in details and also tips are given and discussed. The experimental data is obtained and discussed based on the assumption that the acceleration of a body in a free fall is constant. The method of least square is discussed and exemplified using the available data.
