1. 10-28-11 Warm-Up 5 min Physics Bonus Round Assessment! 20 min
LEARNING GOALS:
The motion of an object depends on the perspective of the observer.
Motion can be represented and analyzed graphically and mathematically.

3. Vocab.
Equilibrant: the one force that brings the net force to equal zero. The equilibrant is equal to but opposite the resultant.
Graphical Representation: using a vector diagram to represent either forces acting on an object or velocity/ acceleration vectors.

4. Vector
Quiz Nov. 1 (B) & 2 (A)

5. Review:
-Vectors requite magnitude (how much) and direction & or orientation.
-Scalar quantities

6. Special Case:
If you are ONLY solving for the equilibrant force, you can use the Pythagorean Theorem to calculate the magnitude of the resultant.
**Use only, if 2 sides are known and direction is NOT needed!

7. PYTHAGOREAM THEOREM
A2 + B2 = C2
C (hypotenuse)
side A
side B

8. For example:
= C2
= C2 ? 3 4
25 = C2
C = √ C = 5

9. X F Y
X and Y are components (vectors)
F is the force that is resolved

10. Y V X
Vector V has components X & Y
