Newton's Second Law of Motion and Physics

The principle that states that a mass acted on by a force undergoes acceleration in the direction of the force, with a magnitude inversely proportional to the mass and proportional to the force is called  Newton's 2nd Law of Motion.

According to Newton's 2nd Law a force that is applied to a mass produces a steady increase in speed. Also decreasing the mass and increasing the force produces a faster increase in speed, while increasing the mass and decreasing the force produces a slower increase in speed.

Every change in motion in the Universe is based on Newton's 2nd Law including both changes in speed and direction. It is indeed fundamental to understanding of motion since without it changes in motion can not be properly understood.

Newton's Laws of Motion They Really Move

The three basic physical laws of classical mechanics are called Newton's Laws of Motion. They describe the relationship between a body, the forces acting on it andhow that affects the resulting motion.

Newton's First law says a body will remain in rest or in motion unless acted on by an out side force. It is also known as the law of inertia since inertia is the resistance to changes in motion.

Newton's Second law says a mass acted on by a force undergoes acceleration in the direction of the force, with a magnitude inversely proportional to the mass and proportional to the force.

Formula

f = ma

f   = force

m = mass

a  = acceleration

Newton's Third law states that for every action there is an opposite and equal reaction.  Put another way when you push on an object it pushes you back. This is the bases of rockets and jets.

 These three laws along with gravity form the cornerstone of modern physics. Not much outside quantum mechanics makes since with out them. They affect every aspect of our lives and are involved in some way with every thing we do.

 The three laws are most evident in space flight. The 3rd law provides force to move a rocket, the 2nd law turns that force into acceleration and the 1st law keeps a space craft in obit or moving through deep space.

In conclusion Newton's Laws of Motion are the three basic physical laws of classical mechanics. They affect every aspect of our lives, in fact we use them every time we move.
