Mathematical Formulation Of Newton S Second Law Of Motion Class 9

Thus newton n kg m s 2.

Mathematical formulation of newton s second law of motion class 9. Mathematical formulation of the second law of motion. Mathematical derivation of second law of motion. Let mass of an moving object be m. Let p1 mu and p2 mv be initial and final momentum respectively.

Therefore 1 newton n 1kg x 1m s 2. Let us say after a certain time t with a constant acceleration the final velocity becomes v. Mathematical formulation of newton s second law of motion. The product of mass and acceleration is the force acting on the object.

In this section we shall learn about the formulation of the second law of motion. Thus newton s second law of motion gives the relation between force mass and acceleration of an object. Let us consider an object of mass m moving along a straight line with an initial velocity u. Consider an object of mass m moving in a straight line with initial velocity u.

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force in the same direction as the net force and inversely proportional to the mass of the object. Therefore change in momentum p2 p1 mv mu. Let be the initial and final momentums respectively.

The unit of mass kg and the unit of acceleration m s 2. F m a v force mass acceleration. The final momentum p 2 m v. Let is initial velocity be u and final velocity be v.

Newton s second law of motion newton s second law of motion can be formally stated as follows. Equation v can be also written as a f m this equation is the form of newton s second law of motion. Let f be force applied on the body. We know that momentum p mass velocity.

Class 9 physics force and laws of motion. According to newton s second law pf pi t f we know that momentum p mv. Force applied is directly proportional to the product of mass and acceleration. It shows uniform acceleration to velocity v in time t.

According to the relation obtained above newton s second law can be modified as follows. Mathematical formulation of second law of motion. Newton n since force mass x acceleration. Here we see that the initial momentum p 2 m u.

If force mass and acceleration is taken as 1 unit.
