A heavy object and a light object in a vacuum are dropped at the same time from rest. The heavy object reaches the ground later than the light object. at the same time as the light object. sooner than the light object.

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.
