- Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

Yes, a heavy object dropped from the same height will fall faster then a lighter one. This is true in the rest frame of either object. You can see this from $F=GmM/r^2=m\cdot a=m\cdot d^2r/dt^2$. The fastest "falling" (since we are re-defining falling) object however is a photon, which has no mass.

Apr 9, 2016 · When you drop a 5 kg body and another 25 tonne body vertically downwards, they will fall under the influence of gravity alone and both will fall with the same acceleration g (free fall). In such a case the weight of the body is zero.
What you may be getting confused by is the fact that the force of gravity is stronger on heavier objects than lighter ones. Another way of thinking of this is to say that gravity has to pull harder on a heavy object than a light one in order to speed them both up by the same amount.
Investigate the effect of gravity on objects of various masses during free fall. Predict what the position-time and velocity-time graphs will look like. Compare graphs for light and heavy objects.
This is a general characteristic of gravity not unique to Earth, as astronaut David R. Scott demonstrated on the Moon in 1971, where the acceleration due to gravity is only .67 m/s2. In the real world, air resistance can cause a lighter object to fall slower than a heavier object of the same size.
In real life, heavier objects sometimes fall faster than light objects, but not because of gravity. Gravity makes all objects increase their speed at the same rate, regardless of how big they are. But if you drop 2 things outside, the air molecules may slow down one thing more than another.
