Free Fall Equation (Vacuum) (Q3794): Difference between revisions

Latest revision as of 13:33, 3 December 2024

a free fall is any motion of a body where gravity is the only force acting upon it, hence neglecting the aerodynamic drag and assuming a uniform gravitational field. Moreover, assuming the falling object to be a point mass.
