Newtons laws of physics
The three laws of physics are known as Newtons Three Laws of Motion. They involve inertia, dynamics and equal and opposite reactions.
They are named after an English Mathematician and Physicist by the name of Newton.
Newtons law... For every action there is an equal and opposite reaction
I am not sure who you are talking about but Newtons laws are very important to physics if that's what you mean.
Yes. Newtons three laws of physics apply to everything in our universe. Only when you study molecular structure and the early formation of the universe do you have to use Einstein's Theories.
His laws basically set the core laws for physics. Without them, we would still not know about momentum, gravity, unbalanced forces, etc. They do sound simple, but they helped to prove certain beliefs at that time wrong and invented a whole new world of physics to explore!
Gravity- shelves, walls etc. newtons laws Signals - voltages, currents from light, TV, computer, speakers etc.
Newtons are a unit of force. They are used in all sort of physics calculations.

Not "the law" - but "the laws", plural. That refers to any of the laws that explain how our Universe works. Read a physics textbook - like the one used in schools - to learn about some of these laws.
Newton's Laws are important because they ae the foundation of modern Physics. Newton's Laws describe Laws that are true throughout the Universe. Newton's laws introduced mathematical models and tools to describe nature.
