Newtons+Second+Law

Newton's second law- Force is equal to the change in momentum per change in time (mV) per change in time. For a constant mass, force equals mass times acceleration. F= ma

Newton’s Second Law of Motion : The acceleration of an object is directly proportional to the resultant force acting on it and inversely proportional to its mass. Σ// F // = // ma // Translation: An object will only accelerate if the net force acting on it is not equal to zero. The sum of all the forces (net force) on the object is equal to the mass of the object multiplied by its acceleration.

 If the mass is a constant and using the definition of acceleration **a** as the change in velocity with time, the second law reduces to the more familiar product of a mass and an acceleration: F = m * a  Since **acceleration** is a change in velocity with a change in time **t**, we can also write this equation in the third form shown on the slide: F = m * (v1 - v0) / (t1 - t0) The important fact is that a force will cause a change in velocity; and likewise, a change in velocity will generate a force. The equation works both ways. The velocity, force, acceleration, and momentum have both a **magnitude** and a direction associated with them.

How is this an example of Newton's second law?
