Sir Isaac Newton 2nd Law Of Motion

Sir isaac newton first presented his three laws of motion in the principia mathematica philosophiae naturalis in 1686.

Sir isaac newton 2nd law of motion.

Sir isaac newton introduced the three laws of motion in 1687 in his book entitled philosophiae naturalis principia mathematica or simply the principia. Newton s second law describes the affect of net force and mass upon the acceleration of an object. Newton worked in many areas of mathematics and physics. Often expressed as the equation a fnet m or rearranged to fnet m a the equation is probably the most important equation in all of mechanics.

His second law defines a force to be equal to the change in momentum with a change in time. Let us assume that we have an airplane at a point 0 defined by its location x0 and time t0. Newton s laws of motion are three physical laws that together laid the foundation for classical mechanics they describe the relationship between a body and the forces acting upon it and its motion in response to those forces. More precisely the first law defines the force qualitatively the second law offers a quantitative measure of the force and the third asserts that a single isolated.

History of newton s laws of motion. The same book also discussed the theory of gravity. Newton s second law is a quantitative description of the changes that a force can produce on the motion of a body. The momentum of a body is equal to the product of its mass and its velocity.

It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. Momentum is defined to be the mass m of an object times its velocity v. He developed the theories of gravitation in 1666 when he was only 23 years old. Some twenty years later in 1686 he presented his three laws.
