Question

what two components define displacement?
○ mass and acceleration
○ distance and time
○ magnitude and direction
○ speed and velocity

Explanation:

Displacement is a vector quantity. Vector quantities are defined by both magnitude (how much) and direction (which way). Mass and acceleration relate to force (via \(F = ma\)), distance and time relate to speed (\(speed=\frac{distance}{time}\)), and speed and velocity are different (speed is scalar, velocity is vector). So displacement needs magnitude and direction.

Answer:

C. Magnitude and direction
