Newtons Second Law

Newtons first legality of motion predicts the behavior of goals for which all active major powers are balanced. The first law - sometimes referred to as the law of inertia - states that if the results acting upon an preyive lens are balanced, then the quickening of that goal leave alone be 0 m/s/s. Objects at equilibrium (the condition in which all forces balance) will not rush along. According to Newton, an object will only rush if there is a straighten out or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing either its amphetamine, its advocate, or both its speed and direction.

Newtons second law of motion pertains to the behavior of objects for which all actual forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends instanter upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased.



As the mass of an object is increased, the acceleration of the object is decreased.

Newtons second law of motion crowd out be formally stated as follows:

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.
This verbal statement can be expressed in compare form as follows:

a = Fnet / m

The above equation is much rearranged to a more familiar form as shown below. The net force is equated to the product of the mass times the acceleration.

Fnet = m * a
