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)
