 Chapter 2
Forces and Newtonâs laws
LEARNING OBJECTIVES
In this chapter you will learn how to:
âtreat bodies as point particles
âconstruct and interpret free-body force diagrams
âapply the equilibrium condition, Î£F = 0
âapply Newtonâs three laws of motion
âsolve problems involving frictional forces
âexplain why we have acceleration in circular motion
âapply Newtonâs laws to circular motion
âidentify centripetal forces.
GUIDING QUESTIONS
âWhat is the connection between force and motion?
âHow does knowledge of the forces on a body allow a prediction of the state of motion of a body?
