Third law of motion

Third law of motion

Each and Every action have its equal and opposite reaction

Just think you are sitting on chair. What forces are creating between you and chair.

There have two force. You are making a force on chair. Let us consider this force as positive force. The chair also will exert a force on you. This force is a negative force.

The mathematical explanation of third law of motion is as follow,

F = - F

Second law of motion

Second law of motion

According to second law of motion by Sir Issac Newton, the rate of change of momentum is proportional to force exerted on it.

Momentum is the product of mass and velocity.

When any massive object became dynamic then its momentum is count as the product of its mass and velocity. 

Momentum is a variable elements that changes. The changes of momentum per time is called the rate of change of momentum. This amount is proportional to force exerts on it.

First Law of motion

First law of motion

If no external force is exerted then static object will be static and dynamic object will be dynamic.

According to First law of motion the change of position of objects is dependent on the force. Force is something that tends to changes the position of objects.

Static objects are these objects that have no velocity. Though, there have no real existence of static object in universe. In our universe everything is dynamic object. Though, something may seem as static, but in really everything is dynamic.

From first law of motion, we find an another definition of the phenomena so called inertia. Inertia is a property of objects to remain its original states. If it in a static state it will tends to be static or it it in a dynamic state it will tend to be dynamic forever.

Newtonian classical mechanics

Once a day all of the theories in physics was based on Newtonian classical mechanics which was also called Newtonian physics or classical physics.

Newtonian classical mechanics is nothing but a study of motion of massive objects.

Basically, Newtonian classical mechanics is three laws of motion developed by Sir, Issac Newton.
