PHYS 1511 Chapter Notes - Chapter 5: Euclidean Vector, Net Force, Kinematics
Document Summary
Chapter 5 of cutnell & johnson"s physics textbook, "two-dimensional forces and. Equilibrium," builds upon the concepts introduced in chapter 4, which covered two-dimensional kinematics. This chapter focuses on forces, which are fundamental to the study of physics, and explains how forces can be used to describe the equilibrium of objects in two dimensions. The chapter begins by defining a force as a push or pull on an object that can cause it to accelerate. The authors explain that forces are vector quantities and can be represented graphically as arrows, with the length of the arrow representing the magnitude of the force and the direction of the arrow representing the direction of the force. They explain that if the net force on an object is zero, then the object is in equilibrium and will remain at rest or move with constant velocity. The chapter then covers the different types of forces, including gravitational forces, normal forces, frictional forces, and tension forces.
