What is newton laws

Newton's laws of motion, named after Sir Isaac Newton, (1642-1727) a British mathematician, physicist, astronomer and natural philosopher, are three physical laws that, laid the foundation for classical mechanics. Newton's third law of motion: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body. Newton's first law of motion: A body continues in a state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it. Newton's second law of motion: The change of motion of a body is proportional to the motive force impressed and is made in the direction of the straight line in which that force is impressed.

Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. 

First law : Every body persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it. 

Second law : The change of motion is proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. 

Third law : To every action there is always opposed an equal reaction: or, the mutual actions of two bodies upon each other are always equal and directed to contrary parts.

A force calculator is a useful tool for calculating the force of many different objects. This force calculator will calculate the force of a spring, a car, a rocket, or anything else that is affected by an external force. The calculator is based on the equation F = ma calculator. This equation states that force (F) equals mass (m) times acceleration (a). But it can be generalized to any object.

Engineers, scientists and students use this online force calculator to calculate the force required to accelerate an object. In the English system of units a force of one pound. One pound force (lbf) is the force that gives a mass of one pound an acceleration of one foot per second per second in the earth's gravitational field. The fundamental units for force in the International System of Units is the newton (N). One newton is the force needed to give a mass of one kilogram an acceleration of one meter per second per second against the earth's gravitational field.
