Unit 4: Advanced Concepts in Forces – friction, components, centripetal force, circular motion and gravity Nov. 28 – Dec. 16
Goals
• Be able to add forces in two dimensions.
• Understand and apply conditions for equilibrium.
• Calculate the frictional force when given the coefficient of friction and vice versa.
• Determine the normal force, and the parallel and perpendicular components of gravity for inclined plane problems and solve for acceleration.
• State and apply equations for centripetal acceleration and force.
• Distinguish between the centripetal force and the fictitious centrifugal force.
• Analyze examples of circular motion in terms of Newton's three laws of motion.
Important Dates
Friction Lab : due Dec. 9
Homework: Dec. 1 and Dec. 12, both at 10:00 pm
Unit Test: Dec. 15
