The total displacement is called the, R

(a)  

Solve (a)   by drawing a scale diagram

Solve (a)   by adding the two magnitudes. We can only do this

because the vectors are in the same direction.

we can still add the two magnitudes. We can only do this because the vectors are ________. We must make one vector

______ to indicate opposite direction.

(a)  

the (a)   is the side opposite

the right angle; the longest side

(a)   is the one across from

a given angle

(a)   is next to a given angle

method for determining the result of adding two vectors that

make a right angle to each other

(a)  

measurement is not always clearly defined

(a)  

M, T, S, D, T, L

(a)  

F, D, V, A, M

(a)  

an instrument should be checked before taking data

(a)  

outside conditions that affect measurement

(a)  

always check the zero reading first

(a)  

come from carelessness, poor technique, or bias on the part of the experimenter

(a)  

repeated measurements produce randomly

different results; observed after repeated measurements; can be processed

statistically using arithmetic mean and

standard deviation.

(a)  

Error that remains constant or changes in regular manner even if measurements are repeated. It causes the measured values to veer away from the accepted or predicted value.

(a)  

with both magnitude and direction.

(a)  

described only by its magnitude and do not have direction. It is represented only by a number with its appropriate unit.

(a)  

describes the quantity or the size of the physical quantity

(a)  

describes how the vector is oriented relative to a reference point; can be given in a written

description, or drawn as an arrow.

(a)  

represents the magnitude of the quantity; vector’s magnitude.

(a)  

show three examples of vectors, drawn to different scales.

(a)  

shortest distance; vector quantity; represented by an arrow.

(a)  

indicates the direction of the vector.
