Question

What is the relationship between \[\vec v_{AB}\] and \[\vec v_{BA}\]?

Options

• Equal in magnitude and direction

• Equal in magnitude but opposite in direction

• Equal in direction but different in magnitude

• No relationship

Answer 1

Equal in magnitude but opposite in direction

Explanation:

According to the characteristics of relative velocity, magnitudes are equal but directions are opposite (\[\vec v_{BA}\] = -\[\vec v_{AB}\]).
