Newton’s Laws of Motion – Force, Mass & Acceleration Explained | Chapter 4 of University Physics Chapter 4 of University Physics introduces Newton’s three laws of motion, establishing the fundamental relationship between forces, mass, and acceleration. This chapter covers the definition of force, the distinction between contact and long-range forces, and how the net force governs the motion of objects. You’ll learn how to apply Newton’s first, second, and third laws and utilize free-body diagrams to analyze complex systems. Defining Force and Types of Forces A force is any push or pull that can cause an object to accelerate. Forces are vector quantities characterized by both magnitude and direction. They include contact forces (such as tension and friction) and long-range forces (such as gravity). To find the net force acting on an object, sum all individual forces vectorially using head-to-tail addition or component methods. Newton’s First Law: Inertia and Equilibriu...
