Question

What are three laws of newton?

Answer 1

First law of motion:- First law of motion is also called as law of intertia.An object continues to be in a state of rest or of motion along a straight line unless acted upon by an unbalanced force.
Second law of motion:- Second law if motion is also called as law of momentum. The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.
Third law of motion:-Third lwa of motion is also called Law of action and reaction. To every action, there is an equal and opposite reaction and they act on two different bodies.

Answer 2

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 said forces. They have been expressed in several different ways over nearly three centuries, and can be summarised as follows.

First law: When viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.

Second law: The vector sum of the external forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object: F = ma.

Third law: 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.
