Inertia :: essays research papers

Centuries of thought and experimentation by several of the greatest minds to ever walk the earth take contributed to the awareness of this property of matter known as Inertia. It all began with the investigation of an ancient Greek scientist and philosopher by the name of Aristotle. Through countless observations and hypotheses, Aristotle grew almost certain of a few things involving inquiry.      Aristotles findings suggested mainly that Earthly objects seek their natural place at rest. This natural place related to earth, water, air and fire respectably. He also believed that motion must be subjected to unnatural absorb, meaning motion could not come about without it. In order to maintain this motion, Aristotle estated that force must be applied to the object constantly. These four statements were considered concrete in the world of physics for nearly two thousand years after Aristotles passing. It would take an Italian physicist and astronomer named Galil eo to eventually disprove his thoughts on motion.      Galileo proposed his formulation of the concept of inertia, which is the property of matter that causes it to resist any change of its motion in either direction or speed. In other words, if an object in a state of motion possesses an inertia, it causes the object to remain in that state of motion unless an external force acts on it. Galileo figured this out by first meticulously observing Aristotles concept of motion. By virtue of a series of experiments, Galileo realized that the analysis of Aristotle was incorrect because it failed to account properly for a hidden force, the frictional force between the surface and the object. For example if one were to propel a block of wood across a table, there would be two opposing forces that act, one of them being the force associated with the push and the other, the force that is associated with the friction, which acts in the opposite direction. Galileo realized a s the frictional forces were decreased the object would move further and further before stopping.      An English mathematician and physicist by the name of Sir Issac normality would after develop Galilieos idea of inertia into one of his three scientific laws. Aware of other factors that played a roll in the theory of inertia, Newton proposed two other laws that supported it. They are included in his famous three laws of motion. The first law of motion states "a body in motion shall remain in motion moving with a constant speed and direction, unless acted on by an outside force".
