TEXTBOOK:  Chapter 6, pages 98 - 106. (Omit Circular Motion.)

OBJECTIVES:

• Exhibit proper procedures in solving problems dealing with multiple forces. 

• Draw a free-body diagram indicating the forces acting on a body when given a force problem.

• Analyze static situations involving friction to determine under what circumstances a body will start to slip, or to calculate the magnitude of the force of static friction.

• Calculate the acceleration of a system of connected bodies and determine the tension in a cord connecting two isolated masses.

• State the relationship between a frictional force and the normal force.

• Analyze situations in which a body slides down a rough inclined plane or is pulled or pushed across a rough surface.

• Solve problems dealing with sliding and kinetic friction.

• Find the terminal velocity of a body moving vertically through a fluid that exerts a retarding force proportional to the velocity.

• Describe qualitatively, with the aid of graphs, the acceleration, velocity, and displacement of a particle in a ‘resistant’ medium when it is released from rest or is projected vertically with specified initial velocity.
