Question

When the point of reference (the observer) is in motion, it flips the "rules" of vector addition (you ADD the vectors going in opposite directions, and SUBTRACT vectors going in the same direction).

True
False

Answer 1

the statement is TRUE

Step-by-step explanation:

When we move in the same direction, the relative speed of the two vehicles is lower, so we must subtract their speeds, if the result is positive the vehicles approach and if it is negative they move away.

v_relative = v₁ - v₂

When the two vehicles go in opposite directions, the speed is much higher, so we must add their speeds

v_relative = v₁ - (-v₂))

v_relative = v₁ + v₂

therefore the statement is TRUE
