Unit 4: Advanced Concepts in Forces

Nov. 30 – Jan. 7
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.
· State and apply Newton's universal law of gravity.
