What does a negative vector mean
The same size as the given vector except in the opposite direction eg -F is the same as F just in the opposite direction
What does a negative scalar mean
A smaller quantity eg -12 degrees is smaller than 12 degrees
What is vector quantity represented by
A vector quantity is represented by a straight line and arrow head
What does the length of a line segment represented in vector quantities
The size of the vector quantity
What does the arrow head represent in a vector quantity
The direction of the quantity
What is the starting point of a vector quantity called
The tail
What is the end point of a vector quantity called (the arrow)
The head
What is a scale vector diagram
When the vectors are drawn accurately according to a suitable scale.
How are vectors indicated
By a symbol of an arrow that pints right above the symbol
What is the resultant
The single vector that has the same effect as two or more vectors together
What is an equilibrant
A vector that has the same magnitude as a resultant but in opposite directions
What are physical quantities
Quantities that are measurable
