Unit 4. More Topic in Forces

This unit focus on various additional topics in forces including inclined planes, adding forces in two dimensions, friction, universal gravity and circular motion.  


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.

Use Newton's Law of Universal Gravitation alone and in conjunction with circular motion equations to describe the motion and forces of planets.
