Forces, Newton`s Second Law
... Until this moment we were always ignoring friction and air resistance in all of the problems we have considered. Now it is time to learn more about frictional force. This is because even if this force is small it is still unavoidable in everyday life. Moreover, this force is, in fact, the one of the ...
