Friction Mass Loss: Formula to Find Lost Mass

[topu87]

When a solid body is moving on any hard surface due to friction it will lose some very little part of its body; as when we take a broken piece of glass and rub it on the concrete surface, it loses some mass of its initial mass. so, what is the general formula of finding the lost mass due to friction of that type?

The mass loss due to abrasion depends on the nature of the materials involved. (I'll move this thread to a more appropriate forum so you'll be more likely to get a useful answer.)
