Weekly Overview

Unit Description      Unit 3    Two-Dimensional Motion and Periodic Motion    

This unit focuses on the analysis of projectile, circular, and harmonic motion plus the use of vectors to

resolve forces exerted at angles.  It also focuses on making calculations using trigonometric functions,

addressing both graphical and mathematical methods.

Essential Questions   Can students:

1.  distinguish between and give examples of scalar and vector quantities?

2.  use triangle trigonometry and scale drawings to resolve vector problems?

3.  solve centripetal force and acceleration problems?

4.  find horizontal and vertical components of projectiles and use these to find distance, time in 

     the air, and launch angles?

5.  analyze the periodic motion of a pendulum and a spring?

6.  resolve torque problems using force and torque arms?

7.  assign relative strengths to fundamental forces?
