The heavy object reaches the ground at the same time as the light object.

Explanation:

When two objects of varying weights are dropped from a height, air resistance normally or usually affects or alters the time it takes for the two objects to land to the ground from the height that they were both released from at once.

If one dropped 2kg Stone and a feather on the moon where there is less air resistance than on earth, the two objects irrespective of their densities will most likely land at the same time on the moon's surface; but on earth where there is a lot greater air resistance, objects with fairly low densities and bigger surface areas will tend to take more time to land to the ground than objects with greater densities as air may put up a force that is strong enough to delay the time it takes for the less dense objects to hit the ground.

It is air resistance that makes most aeroplane manufacturers to design their aeroplanes to have streamlined bodies with narrow faces or noses so as to be able to counter the resistance of air as it travels.

Summarily, if a heavy object and a light object is dropped from the same height in a vacuum (where there's little or no air resistance) the two objects will most likely reach the ground at the same time.

at the same time as the light object

Explanation:

vacuum is a region with a gaseous pressure much less than atmospheric pressure.

In a vacuum, gravity causes all objects to fall at the same rate. The mass of the object does not matter. If I drop for example a heavy stone and a light stone, air will make the light stone fall more slowly. But if there were no air, they would fall at the same rate.

So, When an object falls with air resistance, both its rate of fall and speed change during its motion. When an object falls in a vacuum, there is no air resistance because there is no air in a vacuum.
