hi everyone! I'm new here. I was wondering how energy can be lost to friction? How would one even calculate that? Thanks!

If a car skids to a stop, what form of energy exists beforehand? Is energy in that form lost during the skid?

Can you explain what is puzzling you? If you slide a box along the ground, any kinetic energy is rapidly lost. That seems an obvious example.

It's the difference in work done by the 3rd law pair of friction forces.
