Question

3 multiple choice 1 point according to newtons second law, why do all object fall at the same rate in free fall? the gravitational force pulling on all objects is the same the inertia of all objects are the same on earth. the ratio of the net force (σf) to the mass for all objects is the same all objects fall at a constant velocity on earth

Explanation:

Newton's Second Law is $F = ma$. The gravitational force $F_g=mg$ where $g$ is the acceleration due to gravity. The acceleration $a=\frac{F}{m}$. For gravitational - force $F_g$, $a = \frac{mg}{m}=g$, which means the ratio of the net - force (gravitational force in free - fall) to the mass is the same for all objects.

Answer:

the ratio of the Net Force ($\sum F$) to the mass for all objects is the same
