Tuesday, September 27, 2016 7 Ideas 1. No Force Law a. an object at rest will stay at rest; b. an object in motion will stay in motion (in a straight line). 2. Net Force Law (Most Famous) - A net force will cause an object to accelerate a. the greater the forece, the greater the acceleration; b. the greater the mass, the less the acceleration 3. For Every ACTION, There is an Opposite and Equal REACTION ________________________________________ Unites of Force ( Weight ) English Force Required to accelerate 1 slug mass 1ft/sec^2 Pound (lb) Metric Force required to accelerate a 1 kilogram mass 1m/sec^2 Newton (N) [1 N = 1/5 lbs] Force Required to accelerate a 1 gram mass 1cm/sec^2 Dyne (DY) Remember: In order for all objects regardless of size to fall at the same rate, gravity pulls harder ( with more force ) on more massive (heavier) objects. 1
