... An object moving at constant velocity will continue to move at constant velocity unless and until acted upon by an external force. This may be the most difficult law of all to grasp. In fact, for at least 2,000 years, until the time of Galileo and Newton, the law was simply not recognized by humanki ...

By Newton's 1st Law, if the object is going in a straight line at a constant speed, there must be no net force on it, or else it would speed up, slow down, or turn. For a car going at a steady speed on a straight highway, the force of the ...
