Newton`s First Law of Motion
... Objects are dumb. They do not know the past and they are not good predictors of the future. They only know what forces act on them right now. Newton’s First Law of Motion Every object continues in a state of rest or a state of motion with a constant speed in a straight line unless acted on by an unb ...
