Position and Displacement Vectors

Question

ois the initial position vector

s is the final position vector

Select correct options

Answers

e is the Displacement Vector

Displacement Vector not depend on the actual path undertaken by the object between the two positions

Magnitude of displacement is either less or equal to the path length of an object between A and B

dv

Equality of Vectors

v

Suppose magnitudes of all vectors are same

Select the most suitable terms

vectors do not have fixed locations. So displacing a vector to itself leaves the vector unchanged

In vectors, location or line of application of a vector is important

Vectors A and B are vectors

Vectors A and D are vectors

Vectors A,B and C are vectors
