Paragraph: (Science-textbook/science-g3-7.txt)
Sent 1: Force is a vector.
Sent 2: What then is a vector?
Sent 3: Think about how you would give directions to a friend.
Sent 4: You would not say, just walk half a mile.
Sent 5: The person may walk a half mile in the wrong direction!
Sent 6: More information is needed.
Sent 7: You may say, follow this particular road for a half mile.
Sent 8: You may say, look for the green house on Sumter St. In both examples, you provided a direction.
Sent 9: You also gave the distance.
Sent 10: In other words, you provided a vector.
Sent 11: You did not just give a distance.
Sent 12: Both pieces of information are needed to find a location.
Sent 13: This is just like describing forces.
Sent 14: To explain forces, both size and direction are needed.
Sent 15: Notice the girl in Figure 1.1.
Sent 16: She is pushing the swing away from herself.
Sent 17: Thats the direction of the force.
Sent 18: She can give the swing a strong push or a weak push.

Question: When you say, "Follow this particular road for a half mile," what kind of information are you providing in addition to distance? (true/0)

Direction
Force
Energy
Motion

Question: Why is more info needed to describe a vector? (false/1)

Needs a direction
May we go wrong direction
The person may defy gravity
The person may weigh more
The person may walk a half mile in the wrong direction
The person may be slower

Question: What two pieces of information does a vector provide? (true/2)

Question: What is the direction of force in which the girl is pushing a swing in Figure 1.1? (true/3)

Question: If you know a force magnitude already, then what else do you need in order to give you the knowledge of a vector? (true/4)

Question: What does a strong push or a weak push have to do with force? (true/5)

Connection of the force
Distance of force
Change it's velocity
They both have the same direction
The direction of the force is independent of the amount of force
Motion of the force
It explains the size of the force

Question: How far is the green house on Sumter St.? (true/6)

Question: What is a vector? (true/7)
