Mathematical Formula Of Second Law Of Motion

It is used to predict how an object will accelerated magnitude and direction in the presence of an unbalanced force.

Mathematical formula of second law of motion.

Newton s second law of motion mathematical expression is f α f k mv where k is a constant of proportionality and its value is one in si and cgs system. As we know the rate of change of momentum with respect to time is proportional to the applied force. Students will determine the relationships among force mass and motion. It is equivalent to three equations.

F k md v dt. One for each component of the vectors. F k d mv dt. According to newton s second law of motion force acting on a body is equal to the rate of change of momentum.

Force is directly proportional to rate of change of momnetum that is. The second law then reduces to a more familiar form as follows. For a constant mass newton s second law can be equated as follows. Above is the second law of motion formula.

F k dp dt. F k ma. For a body with a constant mass m force is given by f ma. Newton s second law describes the affect of net force and mass upon the acceleration of an object.

The second law of motion states that the acceleration of a moving body depends upon the mass of the object as well as the force acting on the object. Now according to newton s 2 nd law of motion. The second law of motion is a vector law. F ma.

F ma where f force m mass and. They will also demonstrate and explain the effect of balanced and unbalanced forces on an object in terms of gravity inertia and friction. Newton s second law which states that the force f acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass f ma is the basic equation of motion in classical mechanics. Students will be able to determine the relationship between forces mass and the motion of objects.

The linear momentum of a body is given by. 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.
