!!Newton's Three Laws of Motion!! By Chris Jones

Isaac Newton Born: 4 January 1643( ) Died: 31 March 1727 (aged 84) In mechanics, Newton enunciated the conservation principles of momentum and angular momentum. In optics, he built the first practical reflecting telescope and developed a theory of color based on the observation that a prism decomposes white light into the many colors that form the visible spectrum. He also formulated an empirical law of cooling and studied the speed of sound

Galileo Galilei An Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism. Galileo has been called the "father of modern observational astronomy," [6] the "father of modern physics," [7] the "father of science," [7] and "the Father of Modern Science." [8] Stephen Hawking says, "Galileo, perhaps more than any other single person, was responsible for the birth of modern science."

Three Laws of motion First law There exists a set of inertial reference frames relative to which all particles with no net force acting on them will move without change in their velocity. This law is often simplified as "A body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force." Newton's first law is often referred to as the law of inertia.inertial reference framesforcevelocity Second law Observed from an inertial reference frame, the net force on a particle is equal to the time rate of change of its linear momentum: F = d(mv)/dt. When mass is constant, this law is often stated as, "Force equals mass times acceleration (F = ma): the net force on an object is equal to the mass of the object multiplied by its acceleration.linear momentum Third law Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction. The strong form of the law further postulates that these two forces act along the same line. This law is often simplified into the sentence, "To every action there is an equal and opposite reaction." In the given interpretation mass, acceleration, momentum, and (most importantly) force are assumed to be externally defined quantities. This is the most common, but not the only interpretation: one can consider the laws to be a definition of these quantities. Some authors interpret the first law as defining what an inertial reference frame is; from this point of view, the second law only holds when the observation is made from an inertial reference frame, and therefore the first law cannot be proved as a special case of the second. Other authors do treat the first law as a corollary of the second. [3] The explicit concept of an inertial frame of reference was not developed until long after Newton's death. [3] At speeds approaching the speed of light the effects of special relativity must be taken into account. [note 2]speed of lightspecial relativity [note 2]

First Law

Fun ideas For the first law you can drive a car and slam on the brakes…and the car will stop but you will keep going… For the second law you can push a dump truck that is in neutral and it wont move because of its large mass… For the third law you can push the wall and the wall will push right now…
