Physics is one of my favorite science studies. I can never image Physics without Isaac Newton and his three laws of motion. Newton’s laws are the greatest achievement in history of Physics. The most important reason about those laws is that without them, we can not think about dynamics because it is impossible. I would like to tell you about Newton’s Third Law. The Third Law tells us that: To every action, there is an equal and opposite reaction. I believe that this law works in real life, too. For example, if you treat somebody well, they will treat you well; I am sure because it is like feedback. Ok, let’s see how Newton’sThird Law works. For instance, you push down with your hand on a wall, and the wall pushes upward with a force equal in magnitude to your push. Or when you walk, your feet push the Earth backward. In response, the Earth pushes your feet forward, which is the force that moves you on your way. Finally, I like Physics as a science study because it is really interesting to know how everything works in our Earth.
