Unit 4: Advanced Forces

Unit 4: Advanced Concepts in Forces – friction, components, centripetal force, circular motion and gravity Nov. 15 – Dec. 17

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.
