Question

A 5kg mass is falling freely the force or weight acting will be

Answer 1

Well if the planet is earth where the object is falling freely, the force acting on it can be calculated in the following manner:

Mass of object: 5 kg

Gravitational acceleration on earth: 9.8 m/s

Force acting on the object: mass of object * gravitational acceleration

                                             : 5*9.8

                                             :49 Newtons
