... Newton 2ndlaw of motion The acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object. Example: what force is necessary to cause a 1000 kg car to accelerate at 2 m/s2? F=m a ...

... Newton's Third Law of Motion: There are three laws of motion developed by Isaac Newton. The third one deals with what happens when an object exerts a force on another object. For instance, consider your fist smashing into a thing wall. It might be possible that you punch a hole in the wall. Yet it i ...
