(See Ms. August)
Demonstrate with the speed equation (Speed=Distance/Time) what the term "inversely proportional" means.

5 m/s
If you move 50 meters in 10 seconds, what is your speed?
|
speed is cut in thirds
What happens to the speed if time triples while distance stays the same?
|
The closeness of a measured value to the targeted or accepted value.
Define the term accuracy.
|
Neither
Would the following data set be considered precise, accurate, both, or neither? (Target value= 4 m/s)
5 m/s, 8m/s, 11m/s, 14 m/s |
(See Ms. August)
Demonstrate with the speed equation (Speed=Distance/Time) what the term "directly proportional" means.
|
2 m/s
You arrive in my class 45 seconds after leaving math which is 90 meters away. How fast did you travel?
|
speed doubles
What happens to the speed if time is cut in half while distance remains the same?
|
The overall change in position that includes both magnitude and direction.
Define the term displacement.
|
Precise

43.89 m/s
A plane travels 395,000 meters in 9000 seconds. What was its speed?
|
speed is cut in half
What happens to the speed if distance is cut in half while time remains the same?
|
A vector quantity is fully described by BOTH a magnitude and direction while a scalar quantity is fully described by a magnitude.
What is the difference between a vector quantity and a scalar quantity?
|
Speed: 5 m/s and 8 m/s
Distance: 9 m and 3 m Time: 8 s and 6 s
Organize the following data into groups that represent distance, groups that represent speed, and groups that represent time: 5 m/s, 8 s, 8m/s, 9 m, 6 s, 3 m

(See Ms. August)
On a Time vs. Speed graph, draw a line that represents an inverse relationship.
|
64 km/ hr
It takes Serina 0.25 hours to drive to school. Her route is 16 km long. What is Serina’s average speed on her
drive to school? |
distance doubles
What happens to the distance if speed doubles and time stays the same?
|
Scalar: speed, distance
Vector: velocity, displacement
Using our vocabulary words, give an example of a scalar quantity AND an example of a vector quantity.
|
No because even though distance is remaining the same, while the time increases, speed also increases. However, since time and speed are inversely proportional, if time increases while distance remains the same, speed should decrease.
Look at the following data set on the board. Does this data make sense? Explain why or why not.
