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.

Unit 3- Dynamics
Unit Three – Dynamics
Goals
1. Draw Force Vectors.
2. Calculate Weight.
3. Solve Problems with Net Force.
4. Know that when an object is at rest or moving with constant velocity that Fnet = 0 and all of the forces are balanced.
5. Understand what terminal velocity is and how it is reached.
6. Be able to explain why all objects in freefall have an acceleration of 9.8 m/s2
7. Understand that forces are interactions between two things and that each object exerts an equal and opposite force on the other.
8. Know Newton’s Three Laws of Motion by name.
In general, understand Newton’s 3 laws and apply them to explain motion.
Test Date: Nov. 10
Lab Due Date: Nov. 2 Drafts of sections due at earlier dates. See lab handout.
Homework due in the evening of Nov. 8

Checking Grades
Here is a link to the Parent Assist website.
Many Grant teachers will use this district provided program to maintain and post their grades. You will also be able to monitor attendance and check personal information. I will update grades after every major test and lab, but I might not get every late assignment or retake in the gradebook promptly.
To use this website you will need to get a personal code from the Grant High School office. If you have a code from last year or for any other child it should still be active.
