Simple Machines

Mr. Anderson explains simple machines, starting with a definition of machines and work. He introduces simple machines, their historical context, and the two main types: levers and inclined planes. The video covers mechanical advantage, efficiency, and how simple machines change force direction or magnitude. Examples include levers, inclined planes, and their applications.
