DAY 4

#Goals: SWBAT...

1. Differentiate between an objects speed and velocity

2. Properly set up speed and velocity problems which involve distance and time

3. Convert units when necessary

4. Solve speed and velocity problems with ease

Warm-Up (3min)

1. Which gives more information, a vector or a scalar? What information does it give?
2. Copy each of the following terms, then next to it identify it as a vector or scalar.
   • speed
   • distance
   • displacement
   • velocity

CLASSWORK

HW Questions? (5min)

#004A: (15min) Velocity

- Take notes.

- Complete practice problems

- Presentation is available electronically here --> LINK

#003C continued (this was accidentally printed as #003B, apologies...):

- We will continue practicing with the rest of the 3C problems

- Practice problems 5, 7, 8, 9, 10

QUIZ this Friday on: vectors, scalars, speed, velocity, distance, displacement

Homework answers: (if you have questions, I'm here ~30min before school starts, and all lunch)

1. 25s

2. 4cm/s

3. 60km/hr over the limit

4. 48mi/hr

5. 48mi/hr North

6. 308mi/hr

7. 0 if you consider the question is asking about a round trip, or 308mi/hr North if you think the question is asking about a 1-way trip only.

8. 0.5cm/s, which is 0.005m/s

9. 1610mi West

10. 2m/s West
