Now I get to do something with that force scale I built. I had a request some time ago to talk about friction. Friction is surprisingly complicated. When two surfaces rub against each other, why is ...

New experiments have uncovered a way of controlling friction on ionic surfaces at the nanoscale using electrical stimulation and ambient water vapor. Friction impacts motion, hence the need to control ...

Smooth wooden surface, such as a table or floor (If you do not have a wooden surface, you can use any other type of smooth countertop or table.) Rough carpeted surface (If you do not have access to ...
