The three laws of motion were first compiled by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica, first published in 1687. Newton used them to explain and investigate the motion of many physical objects and systems. The first law states that as object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force. The second law says that the rate of change of momentum of an object is directly proportional to the force applied. The third law means that all forces are interactions between different bodies, or different regions within one body.
About Newton’s laws of motion in brief
The three laws of motion were first compiled by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica, first published in 1687. Newton used them to explain and investigate the motion of many physical objects and systems, which laid the foundation for Newtonian mechanics. The first law states that as object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force. The second law says that the rate of change of momentum of an object is directly proportional to the force applied. The third law means that all forces are interactions between different bodies, or different regions within one body, and thus that there is no such thing as a force that is not accompanied by an equal and opposite force. In some situations, the magnitude and direction of the forces are determined entirely by one of the two bodies, say Body A; the force exerted by Body A on Body B is called the “action” and the force exerted by Body B on Body A is known as the “reaction” This law is sometimes referred to as the action-reaction law, with FA called the \”action\” and FB the \”reaction\”. In other situations, such as in the case of a car and a person walking on a road, the two forces are of the same type, and it isn’t necessary to identify one force as the ‘action’ and the other as’reaction’ The two forces in Newton’s third law are seen when a person walks against the floor, pushes against the road, and simultaneously pushes back on the tires of the car.
These forces are called the reaction and are part of a single interaction, and are neither part of the action nor the reaction, which is neither called the action or the reaction. In these examples, these forces in motion are seen as the reaction for the motion in these examples and for these reasons they are called Newton’s laws for motion. Theory of Newton’s Laws of Motion is published in the book The Theory of Motion, published by Oxford University Press, priced £9.99, with an MSRP of £16.99.
