1. Agenda Tuesday 4/2/13: Motion
1) Warm-up- CST 15 min
2) Focus Question & Set up notebooks – 15 min
3) Motion Activity – 40 min
4) Notes – 20 min
5) Worksheet and Answer Focus Question – 20
min

2. Set up notebooks
Objective: How do we find average speed?
Focus Question: Usain Bolt set the olympic record
for the 100m dash at 9.63 seconds. What was his
average speed?

3. We will now read the activity
worksheet as a class
Right now: Decide who will be the runner, walker,
and skipper for your group, and who will time the
first set of trials.
Watch Mr. Lee demonstrate how to use the
stopwatch.

4. Notes
Copy all the notes in green

5. In physics, we use the term velocity to describe
an object in motion. Velocity describes how fast
and in what direction an object is moving.

6. Velocity has two parts: Speed, which tells us how
fast the object is moving, and Direction, which
tells us which way the object is moving.

7. Average speed tells us how fast an object was
moving, on average, from start to finish.
Average speed is TOTAL DISTANCE divided by
TOTAL TIME. Avg. Speed = D/T

8. If you knew the average speed of an object, and
the total time it was in motion, could you find the
distance it traveled?
Copy the formula and directions on your
homework sheet.

9. A graph of speed gives you information on
distance, time, and speed of an object.

10. Worksheet
Complete the worksheet with your partner. One
person will answer the first question, then his/her
partner will answer the next question. Follow this
pattern for the entire worksheet. I should see
alternating handwritings when it is turned in. Time:
20 minutes

11. Answer Focus Question
One student will now answer the Focus Question
for the day.
