This law is also known as the law of inertia, and it states that an object's state of motion will not change unless an external force is applied.

The Newton is defined as the force required to accelerate a mass of one kilogram by one meter per second squared.

This law is expressed mathematically as F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.

This equation is known as Newton's Second Law of Motion.

This law means that when one object exerts a force on another object, the second object exerts a force of equal magnitude but opposite direction on the first object.

This relationship is expressed mathematically as F = Gm1m2/r^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them.

The kilogram is defined as the mass of a specific platinum-iridium cylinder kept at the International Bureau of Weights and Measures in France.

Acceleration is the rate of change of velocity, and is measured in meters per second squared.

Friction is a non-conservative force, meaning that it does work on an object and converts some of its kinetic energy into heat.

The coefficient of friction is a measure of the force required to overcome friction between two surfaces.

Isaac Newton published his laws of motion in his Principia Mathematica in 1687.

The laws of motion are the foundation of classical mechanics, which describes the motion of objects in the everyday world.

The laws of motion have been used to explain a wide range of phenomena, from the motion of planets to the operation of rockets.

The laws of motion are still used today in a variety of fields, including engineering, physics, and astronomy.

The laws of motion are considered to be one of the most important and fundamental theories in physics, as they provide a framework for understanding the motion of objects in the universe.
