Phase 1

a) Outline the differences between vector and scalar quantities. R: Scalar quantities only have a magnitude, while vector quantities have both magnitude and direction. Scalar quantities cannot be negative

b) What meaning do concurrent and non-concurrent vectors have?

c) How does the magnitude of the result between two vectors changes if the angle between them decreases?

d) What is the sum of 3 vectors that form a closed triangle?

e) What is the procedure for adding 2 concurrent vectors?

f) What is the procedure for adding 2 non-concurrent vectors?

g) If 2 force vectors have magnitudes of 8N and 10N, to what angle would the magnitude of the resultant be maximum? And, to what angles would it be minimum?

h) Under which condition of magnitude of a vector is equal to the magnitude of 1 of its components?

i) If a vector F is drawn on a plane xy, what range of values can take angle if:

I. Its components x and y are both positive? R: the results will be located on the first quadrant, in other words between 0 ° and 90°, with the +x-axis.

II. Its components x is positive and its component y is negative? R: The resultant will be located on the second quadrant, this is, its direction will be between 90° and 180°, with the +x-axis.

III. Its components x and y are both negative? R: The resultant will be located on the third quadrant, between 180° and 270° with the +x-axis.

IV. Its components x is negative and your component y is positive? R: The resultant will be located at the fourth quadrant, and its direction between 270° and 360° with the +x-axis.
