Which of the following are vectors?

Question

(select all that apply)

1. the height of a building

2. the velocity of a sports car

3. temperature

4. force

5. the volume of water in a can

6. the ratings of a TV show

7. the age of the Universe

Vectors require both magnitude and direction. I chose 2, 3, 6 because all could have a direction and magnitude. What am I choosing wrong or not choosing?

Answer 1

2 3 4 5  are  the vector  

Answer 2

Vectors:

2 and 4

None of the others have a direction. Velocity is speed in a direction, force is mass*acceleration in a certain direction. All of the others are scalars (that is, pure numbers without direction).

Answer 3

Vectors have magnitude and direction.

they obey law    of vector additions etc

1)  scalar

2) velocity is a vector

3) temperature  is scalar

4) vector

5)scalar

6)  7) scalar

Answer 4

2 is a vector because the car is doing 60 mph and going THAT way.

3 is not a vector. It is a scalar. It does not have a direction.

4 is a vector. A force has a magnetude and acts in a certain direction.

6 is not a vector.  

Answer 5

Ahhhh the ol' scalar versus vector quantities.  I get a kick out of the idiot talking head weather personalities who often state (in the midwest mostly) "wind chill factor".  I pose the question to you, what is wrong with this?  In answering my question, you just may discover the answer to yours.
