A) Galileo Reading Quiz Newton's 1st Law You kick a smooth flat stone out on a frozen pond. The stone slides, slows down, and eventually stops. You conclude that: A) the force pushing the stone forward finally stopped pushing it B) no net force acted on the stone C) a net force acted on it all along D) the stone simply “ran out of steam” E) The stone has a natural tendency to be at rest Newton's 2 nd Law Newton's 2 nd Law: Solving problems with this: 1) Sketch the Forces 2) Isolate the particle of interest 3) Choose a convenient coordinate system 4) Resolve Forces into components with this coordinate system 5) Apply the 2 nd law to each component ! F = m ! a
