In a vacuum, an object will move faster than an identical object in a medium with resistance, such as air. This conclusion is based on the principle that viscous losses in a non-vacuum environment impede motion. When two equal objects are subjected to constant speed without external net forces, the one in a vacuum will maintain its speed more effectively due to the absence of friction and drag forces. Therefore, for optimal speed, a vacuum is preferable.
