Vectors and scalars

Question 1

What is a Vector?

Answer 1

A quantity that requires both a magnitude and direction to be fully specified

Question 2

What is a Scalar?

Answer 2

A quantity that requires only a magnitude to be fully specified

Question 3

Examples of scalars

Answer 3

Mass
Time
Volume 
Density 
Distance
Speed

Question 4

Example of vectors

Answer 4

Weight (force)
Displacement
Velocity
Acceleration

Question 5

What is the arrow showing on a vector?

Answer 5

the direction of the arrow indirection of the vector and the length, the magnitude of the vector

Question 6

Co-linear or same line

Answer 6

two vectors are in the same direction.
The vectors are connected tip to tail. The resultant, R, has a magnitude equal to the sum of the magnitudes and a direction the same as the original direction.

Question 7

Perpendicular

Answer 7

triangle
The vectors are connected tip to tail. The resultant has a magnitude tat is determined using Pythagoras and a direction determined by trigonometry.

Question 8

steps when adding vectors

Answer 8

1. Resolve each vector into its X and Y components
2. Add each X and Y component arithmetically
3. Add the resultant components to bet your resultant vector
