free fall is a situation in which the only force acting upon an object is gravity. why do all objects in free fall have the same acceleration? a their masses are always the same b acceleration due to gravity is always the same c the distance between two objects is always the same d the gravitational force between two objects are always the same
Answer
# Brief Explanations:
According to Newton's second - law and law of universal gravitation, near the Earth's surface, the acceleration due to gravity ($g$) is constant for all objects in free - fall regardless of their mass. The gravitational force $F = mg$ and $F=\frac{GMm}{r^{2}}$, and when we calculate the acceleration $a=\frac{F}{m}$, the mass $m$ cancels out, resulting in a constant acceleration due to gravity.
# Answer:
B. acceleration due to gravity is always the same
