Unit Four: Advanced Topics in Forces

Dec. 2 - Jan 8
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.

Unit Three Description

Sorry. This should have been put up a month ago.

Goals
Draw Force Vectors.
Calculate Weight.
Solve Problems with Net Force.
Know that when an object is at rest or moving with constant velocity that that Fnet = 0 and all of the forces are balanced.
Understand what terminal velocity is and how it is reached.
Be able to explain why all objects in freefall have an acceleration of 9.8 m/s2
Understand that forces are interactions between two things and that each object exerts an equal and opposite force on the other.
Know Newton’s Three Laws of Motion by name.
In general, understand Newton’s 3 laws and apply them to explain motion.
