Linear Motion Review Part 1
1. Describe what each of these branches of physics study
a.) thermodynamics
b.)mechanics
c.)quantum mechanics
d.) optics
2. Complete the SI Units Chart
distance
grams
seconds
speed
3.Express the following in scientific notation
a.) 340,000,000,000,000
b.).000546
c.)-15400
4.)Take the following out of scientific notation.
a.) 1.8 X 10-6
b.) 7.9 X 108
c.) 3.2 X 103
5. Calculate the following and put the answer in correct scientific notation
a) 1.2 + 45.6 + 3.2
b) 9.32 X 106 x 2.3 X104
c.) 5.6 X 107 x 1.2 X 10-3
d.) 2.3 X10-5/ 1.6 X 104
6.When reading a graph what are the first 2 things you need to look at on the graph in
order to analyze the information?
7.
You are running errands and leave your house and drive 3 kilometers west and
then you turn south and drive 6 kilometers. You get out and run into a store to
grab some bread and then get back in your car and drive 3 kilometers east. What
is your total distance traveled? What is your displacement from your starting
point?
8. What object in your car gives you instantaneous speed? How is this different
from average speed?
9. In a distance/time graph what does the slope of the line indicate?
10. 4 friends were competing to see who could speed walk the fastest. They created a
track with a 5m and 10m mark and then timed each other speed walking those
distances. They recorded their data in a chart. Create a distance time graph with
the following data. You should have 4 separate lines on your graph, one for each
friend.

Now using the graph you created please answer the following questions
1. Using the graph give me Sue’s average speed for speed walking
2. Who won? Who was the slowest? How can you tell by just looking at the graph
you created?
3. If John speed walked at that speed for 25 seconds, how far would he travel in
meters?
4. How long would it take Molly to travel 50 meters at her average speed?
