Vectors: Day 1

Question 1

What is the difference between a vector and a scalar?

Answer 1

vector- both magnitude and direction (ex.displacement,velocity,force)
scalar- magnitude but no direction(ex. d,v,age,temp.)

Question 2

what is the difference between equivalent vectors and opposite vectors?

Answer 2

equivalent- same mag and direction

opposite- same mag, opposite direction

Question 3

How do you determine a quadrant bearing on a graph?

Answer 3

[N20E]- start from N and go “x” (20) degrees E

Question 4

How do you add and subtract vectors? (diagram ones)

Answer 4

• vectors are added tip to tail (where one ends, next one starts)
• think of the subtracted vector as the opposite vector and then add
• follow the path of vectors from starting vector letter to ending vector letter*

Question 5

What are scalar multiples of vectors and how do you treat them?

Answer 5

ex. 2a is a scalar multiple of A as it is double the mag of the A vector and in the same direction.
- we can combine vectors like “like” terms
- distributive property applies to vectors
