PHYS 1511 Chapter Notes -Net Force, Centripetal Force
Document Summary
Chapter 3 of cutnell and johnson"s physics, young & stadler, vol. 1, 11th edition, introduces the concept of force, including its measurement, description, and analysis. The chapter begins by defining force as a push or a pull on an object that causes it to accelerate, and introduces the idea of a force diagram, which is used to represent the forces acting on an object. The authors explain how this law applies to objects in one and two dimensions, and provide examples of how it can be used to analyze the motion of objects. The chapter then moves on to discuss newton"s second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass. The authors explain how to calculate the acceleration of objects using this law, and provide examples of how it can be used to analyze the motion of objects in different situations.
