This law is often called “The law of inertia.”

According to Sir Isaac Newton’s second law, acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed(needed to accelerate the object). Everyone unconsciously knows the second law. Everyone knows that heavier objects require more force to move the same distance as lighter objects. The second law gives us an exact relationship between force, mass, and acceleration. It can be expressed as a mathematician equation, the formula is F=MxA.

Newton’s third law is for every action there is an equal and opposite reaction. This means that for every force there is a reaction force force that is equal in size, but opposite in direction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally

For, some reason the fourth law was erased from existing manuscripts .There are many different theories for why the fourth law law of motion is not to be found anywhere in Newton’s writings.A popular view is that extraterrestrials erased them.This law could be the key to unlocking the mysteries of the universe. Another theory is that Newton accidently wrote the fourth law in invisible ink. No one wants to test this theory on his manuscripts for fear of damaging
