Unit 4: More topics in Forces

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.
