Answer is C
Regardless of their size, all free falling objects on Earth accelerate downwards at the same rate.
Gravity Summary
· Essentially, gravity is the constant downward force that keeps people and objects on the Earth.
· The force of gravity is such that it will create resistance for any other force or effort that tries to elevate an object above a resting point.
· In general, the force of gravity exerted upon every object is the same, regardless of the object’s weight, size, shape, etc. Thus, objects moving only by the force of gravity (i.e., in free fall) will move at the same rate toward a resting point.
