Sir Isaac Newton 2nd Law Of Motion

Newton s second law describes the affect of net force and mass upon the acceleration of an object.

Sir isaac newton 2nd law of motion.

The same book also discussed the theory of gravity. He developed the theories of gravitation in 1666 when he was only 23 years old. 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. Some twenty years later in 1686 he presented his three laws.

Let us assume that we have an airplane at a point 0 defined by its location x0 and time t0. Newton s second law is a quantitative description of the changes that a force can produce on the motion of a body. Momentum is defined to be the mass m of an object times its velocity v. 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.

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. His second law defines a force to be equal to the change in momentum with a change in time. 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. Newton worked in many areas of mathematics and physics.

It is used to predict how an object will accelerated magnitude and direction in the presence of an unbalanced force. History of newton s laws of motion. This one volume described the main rules still used in classical mechanics today. 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.
