This chapter gets enlightened about the 3 fundamental laws of motion proposed by Newton. The chapter starts with a briefing about the two forces, namely – contact and non-contact forces, discussing the various types of forces under each along with suitable examples. Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to forces. The laws are: In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction. Newton's laws are essential because they relate to everything that we do or see in everyday life. These laws tell us how things move or stay still, why we don't float out of our bed or fall through the floor of our house. Newton's laws of motion imply the relationship between an object's motion and the forces acting on it.
