... An object in motion stays in motion unless acted upon by an unbalanced force. For every action, there is an equal and opposite reaction. A constant net force acting on an object produces a change in the object’ s motion. Energy is neither created not destroyed; it simply changes form. ...

QUICK QUIZZES 1. Newton`s second law says that the acceleration
... Newton’s second law says that the acceleration of an object is directly proportional to the resultant (or net) force acting on. Recognizing this, consider the given statements one at a time: (a) True— If the resultant force on an object is zero (either because no forces are present or the vector sum ...
