Question 1

How does the addition of a a scalar and a vector quantity differ?

Answer 1

The addition of velocity depends on direction

Question 2

What do the lenght of the line and the direction of the arrow line represent in a vector?

Answer 2

Lenght is the magnitude of the vector drawn to scale.
The arrow head shows the direction of the vector

Question 3

How are parallel vectors added?

Answer 3

Two vectors acting on the same line and direction are just added together to find the resultant vector. The direction of the resultant will be the same but its magnitude greater.

Question 4

How are antiparallel vectors added?

Answer 4

Call one direction positive and one negative (assign positive and negative values) , then add them together to find the resultant. Magnitude and direction will depend on the magnitude of the two vectors

Question 5

What is meant by antiparallel vectors?

Answer 5

They act on the same line but in opposite directions
