DAY 13

***It's week four. Grades go in this week, and progress reports come out next week. How are your quiz scores? Did you answer all the lab questions correctly? Think about how the class is going, and make any necessary adjustments.***

ESSENTIAL QUESTION:

In which ways can we answer the question, "How far?"

In which ways can we answer the question, "How fast?"

#Goals: SWBAT...

1. Define scalars/vectors & distance/displacement

2. Solve speed and velocity problems with ease

3. Convert units when necessary

WARM-UP

Which of the following statements about vectors and scalars are TRUE and which are FALSE? Copy the true ones into your warm-up

1. A vector is a large quantity and a scalar is a small quantity.

2. A scalar quantity has a magnitude and a vector quantity does not.

3. A vector quantity is described with a direction and a scalar is not.

4. Scalar quantities are path dependent quantities and vector quantities are not.

5. A scalar quantity depends only upon the initial and final values of the quantity; this is not the case for vector quantities.

6. The quantity 20 m/s, north is a speed and as such is a scalar quantity.

CLASSWORK

1. Review: Speed and Velocity Worksheet

2. #013A: Practice Problems: 

    Review & Check your Understanding of this week's topics here: LINK

    Check your answers to #1 (this was the warm-up) and complete #'s 2, 3, 13, 16, 17, 19

3. #013B: Design an Experiment (6 min)

Every time a particular red motorcycle is driven past your friend’s home, his father becomes angry because he thinks the motorcycle is going too fast for the posted 25 mph (40 km/h) speed limit. In your notes, describe a simple experiment you could do to determine whether or not the motorcycle is speeding the next time it is driven past your friend’s house.
