The present article intends to show the implementation of one of the subjects for physics in high school, where it is detected difficulty to be assimilated and related to the environment, so this subject that corresponds to free fall is worked in theoretical and experimental aspects to develop in the physics students, concepts and applications of notions such as gravity, weight, mass, and forces acting on bodies when falling in the presence of a gravitational field. Three practical and simple experiments together with mental experiments serve as the stage to develop these notions and thus find relationships with the environment.
