By definition, internal force is whatever causes an object with mass to accelerate or move. This force is equal to the product of the mass of the object plus its rate of acceleration.
Continue ReadingThe first studies of force date back to the third century B.C. and the philosopher Archimedes. Some of his ideas are still found in modern mechanics and physics today. Years later, Aristotle's original findings about force were corrected by the discoveries of Isaac Newton. Isaac Newton's findings depict four fundamental kinds of force: strong, electromagnetic, weak and gravitational. His descriptions have remained largely unchallenged to this day.

Full Answer >The net force of an object can be determined if the mass and acceleration are known. Net force is determined by multiplying the mass of the object by its rate of acceleration.
Full Answer >The force of gravity between two objects is determined by the mass of each object and the distance between their centers. Objects with a greater amount of mass will exert a greater degree of gravitational pull, but as the distance between two objects increases, the gravitational force between them lessens. The significance of distance with regard to large masses, such as planets, plays an important role in the science of Astronomy.
Full Answer >According to NASA, Newton's three laws of motion are: an object in motion tends to stay in motion, force equals mass times acceleration and for every action there is an equal and opposite reaction. Together, these three laws form the basis for classical mechanics.
