Question

What is Newton law

Accepted Answer

Newton's laws of motion are three fundamental laws that describe the relationship between a body and the forces acting upon it.

First law: An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force.
Second law: The acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass.
Third law: For every action, there is an equal and opposite reaction.
Examples: A ball rolling on a flat surface will continue to roll until friction or another force stops it (first law). Pushing a shopping cart requires more force to move a heavier load (second law). When a rocket expels gas out of its engines, the gas pushes back on the rocket, propelling it forward (third law).
