2. What is a vector? Direction and magnitude
Direction - course of movement
Magnitude - size or extent of something

3. Velocity
The speed of something in a given direction
Speed + direction

4. Weight
Weight = Mass * Fgravity

5. How to: Vectors Dot shows where the force begins
Length of the arrow shows the amount of force
Arrow shows the direction of the force

6. Vectors Practice: 7N

7. Vectors Practice: 7N
Place the dot

8. Vectors Practice: 7N Place the dot
Draw a line from the dot that is seven squares in length

9. Vectors Practice: 7N Place the dot
Draw a line from the dot that is seven squares in length

10. Vectors Practice: 5N

11. Vectors Practice: 5N
Place a dot

12. Vectors Practice: 5N Place a dot

22. Resultant Vectors Calculate the net force first
Then draw the resultant vector

23. Resultant Vector Example: #1
2 total forces
4N to the right
10N to the right
Fnet = 4N + 10N = 14N, right
Resultant vector - 14N, right
Movement? Right

25. Check your answers: #2 2 forces 8N right 13N right
Fnet = 8N + 13N = 21N
Resultant = 21N
Movement? Right

26. Check your answers: #3 2 forces 11N left 9N right Fnet = 11N-9N, left
Resultant = 2N
Movement? Left

27. Check your answers: #4 2 forces 6N up 6N down Fnet = 6N - 6N = 0N
Resultant = 0N
Movement? None

28. Check your answers: #5 3 forces 2N up 5N up 5N down 2N + 5N = 7N
Fnet = 7N - 5N = 2N
Resultant = 2N
Movement? Up

29. Check your answers: #6 2 forces 5N down 6N down Fnet = 5N + 6N = 11N
Resultant = 11N
Movement? Down
