Question 5

5.

Categorize the following into scalar and vector quantity's.

The beaker has a volume of 500ml.
The time is 2:30pm.
He threw the baseball 85 miles per hour.

Scalar Quantity (mangitude/size only)

Question 6

6.

Mikes room temperature. Which of these descriptions describes temperature in terms of a vector quantity (a quantity with size and direction)?

Question 7

7.

Surfs up. Which of these descriptions are vector quantities?

Jandy rode down the southeast wave at a velocity of 20 meters per second.

Question 8

8.

"Jonathan measured the wall in his room to be 9 and ¾ feet."
Why is this statement not a vector?

Direction is not mentioned.

There is size but not magnitude or strength mentioned.

Height is a measurement that is not continuous so it cannot be a vector.

Question 12

12.

For each question, add (same direction arrows) and subtract (opposite direction arrows) to get the units. Then draw the correct arrow direction and size associated with the units.

Question 13

13.

For each question, add (same direction arrows) and subtract (opposite direction arrows) to get the units. Then draw the correct arrow direction and size associated with the units.

Question 14

14.

Which of these would be the correct vector after adding and subtracting?

Question 15

15.

Which of these would be the correct vector after adding and subtracting?

Question 16

16.

Messi is a beast!!! Draw a displacement line from Messi to where he is after making the goal.

Question 17

17.

Draw the line of displacement of Rigby and Mordecai’s lawn mowing path.

Question 18

18.

Draw the lines of displacement and label them appropriately!!!

a) Draw the displacement line from B to C (label the line a)
b) Draw the displacement line from C to G (label the line b)

Question 19

19.

Why is the displacement zero if a person traveled from A to B to C to D to G to F to E and then back to A?

The displacement is not zero. It is a value not represented here. Displacement is the total distance traveled from start to finish.  Here the total distance travled is A added to all points. 

Displacement is different than distance in the sense that displacement has direction and is a vector, while distance is a scalar.

The displacement is the shortest distance from where you started to where you end and it will always be zero if you end where you started.

Misty rode her bicycle at a speed of 35 miles per hour.

Scalars are measurements that are fully described by _________ (strength only).

* Examples include: _____, distance, mass, energy, density, temperature.

power; drag force

force; size

magnitude; speed

measurment; quantity

Question 4

4.

Vectors are measurements that have magnitude and _.

* Examples include: _, force, displacement, acceleration, gravity.

range; humidity

The sprinter clocked in running 30mph east.

Jona carried the fridge with a force of 3000N upward on his shoulder until he got home.

Vector Quantity (magnitude/size and direction)

Colder temperatures are more prevalent in the morning than in the afternoon.

The temperature was -15oC

The temperature increased or went up from what it was before.

The temperature of Mikes room was -15oC, which is cold in the morning but then it got hot.

The temperature went up from -15oC to 25oC.

Timmer noticed that the water was 15oC and he almost caught a cold while surfing.

Before surfing Jan calculated the force of the southern facing waves to be 1543 Newtons. The North waves had a force of 2000 Newtons.

Condy was surfing, a huge wave was directed at her on the northside of the harbor.

Kara noticed that the distance from the shore to first large wave was 25 feet.

In this case, height is a vector because of the size mentioned.

Question 9

9.

Objects always go in the direction of the ______ vector arrow.

greater

smaller

volitile

sharper

Question 10

10.

Vector arrows with the same direction can be _____ together.

added

subtracted

divided

multiplied

Question 11

11.

Vector arrows with opposite directions must be ________ from each other.

Added

Subtracted

Multiplied

Divided

The displacement is zero because it is a vector.

size; energy

direction; velocity

motion; speed

energy; salinity
