1 Force and Motion in 2-D

2 Vector vs. Scalar

3 Vectors are unequal if…
Vectors are equal if… Vectors are unequal if…

4 Equal vectors Same magnitude Same direction Note: slope
Equal vectors Same magnitude Same direction Note: slope Negative vectors Same magnitude Opposite directions Note: slope

5 Vector Addition Examples
Vector Addition with three vectors.

6 Vector Addition Add vectors tip-to-tail
Draw resultant vector from tail of first vector to tip of last vector

7 Vector Addition Draw x and y components of resultant
Use Pythagorean Theorem A2 + B2 = C2 (C is the resultant vector)

8 Sample Problem A car is driven 100 km due west, then 35 km due south. What is the magnitude and direction of its displacement? Solve the problem graphically. Calculate the magnitude. 5 10 15 20
