# Newton’s Laws of Motion and Car Physics

Sir Isaac Newton is perhaps most well-known for his three laws of motion. These three laws of motion are part of the field of physics, a type of science that people don’t often think about in their everyday lives. But Newton’s laws are very important, especially when it comes to the creation and safety of new cars. Newton’s laws of motion deal with how objects move when some sort of force is used on them. Each of these laws must be considered to ensure that cars are made in a manner that they can move efficiently while on the road (the first law), can speed up properly (using the formula in Newton’s Second Law), and are able to stop quickly when the brakes are used (the third law). Without understanding these laws of motion, it would be very hard to create and maintain vehicles.
