FUNDAMENTALS Newton’s Law law: Every object in a state of uniform motion tends to remain in that state of motion (i.e., either is at rest or moves at a constant velocity) unless an external force is applied to it. Second law: The sum of the forces on an object is equal to the total mass of that object multiplied by the acceleration of the object, i.e., the acceleration of a body is directly proportional to the net force acting on the body, and inversely proportional to its mass. Thus, = ma ΣF Where, =is the net force acting on the object. ΣF m= is the mass of the object, and a =is the acceleration of the object. Force and acceleration are both vectors (as denoted by the bold type). This means that they have both a magnitude (size) and a direction relative to some reference frame. Third law: For every action there is an equal and opposite reaction.
