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. Let us assume that we have an airplane at a point 0 defined by its location x0 and time t0. Some twenty years later in 1686 he presented his three laws. Newton s second law describes the affect of net force and mass upon the acceleration of an object. He developed the theories of gravitation in 1666 when he was only 23 years old.

His second law defines a force to be equal to the change in momentum with a change in time. 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. Sir isaac newton introduced the three laws of motion in 1687 in his book entitled philosophiae naturalis principia mathematica or simply the principia. It is used to predict how an object will accelerated magnitude and direction in the presence of an unbalanced force.

Momentum is defined to be the mass m of an object times its velocity v. 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. The motion of an aircraft through the air can be explained and described by physical principals discovered over 300 years ago by sir isaac newton.

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. This one volume described the main rules still used in classical mechanics today. The same book also discussed the theory of gravity. Newton worked in many areas of mathematics and physics.
