Question

If an object moves from position r₁​ to r₂​, what is the correct expression for its displacement vector, Δr?

Options

• r₁ + r₂

• \[\frac {{r_2}+{r_1}}{2}\]

• r₁ - r₂

• r₂ - r₁

Answer 1

r₂ - r₁

Explanation:

Displacement is defined as the final position vector minus the initial position vector.
