Chapter 3 The Laws of Motion
You will now begin to study the laws that govern how forces impact motion.
Objectives
After successful completion of this chapter, you will be able to:
-
Differentiate between contact forces and non-contact forces
-
State and apply Newton’s laws
-
Draw a free-body diagram of an object or multiple objects in a system
-
Define the normal force acting on an object in various situations
-
Break a vector into appropriate components
-
Construct net force equations in multiple dimensions for an object based on its acceleration and its free-body diagram
-
Solve net force equations symbolically in terms of given variables
-
Use special-case analysis to make sense of a symbolic equation
