Do falling objects drop at the same rate (for instance a pen and a bowling ball dropped from the same height) or do they drop at different rates? I know a feather floats down very slowly but I would think a heavy object would fall faster than a light object.

Near the surface of the earth g is the same for all objects. All objects accelerate at approximately the same rate. Freely falling objects are therefore objects, which are moving with constant acceleration g.

So all objects, regardless of size or shape or weight, free fall with the same acceleration. In a vacuum, a beach ball falls at the same rate as an airliner. Knowing the acceleration, we can determine the velocity and location of any free falling object at any time.

Question: Why does gravity pull a heavy and light object down to the Earth at the same rate so that they hit the ground at the same time? john i swang phd Answer 1: The heavy and light objects travel at the same rate because there are two competing factors that cancel each other out.

But if one more accurately defines "falling rate" as the closing speed between two objects (when they are allowed to move freely by the force of gravity), then objects do not fall at the same rate. The closing speed must involve the acceleration and movement of the other object too.

All objects, regardless of mass, fall to the ground with the same acceleration, as long as air resistance is not a factor. This is because gravity pulls all falling objects down to earth at the same rate.

For the natural motion of heavy objects falling to earth, Aristotle asserted that the ... Having established experimentally that heavy objects fall at practically the same rate, Galileo went on to consider the central question about speed of fall barely touched on by Aristotle---how does the speed vary during the fall?

What is the acceleration of a free falling object on earth? What is the rate of acceleration when an object falls to earth? How do you find the acceleration of a falling object gainig 9.8ms? When objects are falling downward what is the rate of acceleration?

Because free-falling objects are accelerating downwards at a rate of 9.8 m/s/s, a ticker tape trace or dot diagram of its motion would depict an acceleration. The dot diagram at the right depicts the acceleration of a free-falling object.
