Document Summary
Chapter 2- newton(cid:495)s first law of motion- inertia in class notes. Galileo showed that stuff falls at the same (cid:494)rate(cid:495) regardless of their initial mass: got rid of air resistance, 10 meters per seconds ^2. A body at rest, wants to stay at rest. A body in motion, wants to stay in motion: example coin dropping into glass with card, tightening the hammerhead, ball on wagon. A space probe is carried by a rocket into outer space. It(cid:495)s a property of all matter to resist changes in. Equlibrium does not mean no force are acting, but that the sum of all the motion. forces is equal to 0. Gravity pulls it down the table keeps it up: normal force. Supporting force: example: man on scale. Dynamic equilibrium has the same condition as static equilibrium. Plane moves at constant speed if thrust= drag: ex.
