This unit focus on various additional topics in forces including inclined planes, adding forces in two dimensions, friction, circular motion, and Newton's Universal Law of Gravitation.
Goals
• Be able to add forces in two dimensions.
• Determine the normal force, and the parallel and perpendicular components of gravity for inclined plane problems and solve for acceleration.
• Calculate the frictional force when given the coefficient of friction and vice versa.• 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.
• Solve problems with Newton's Universal Law of Gravitation.
