Question

displacement is to velocity as ______ is to acceleration.
a direction
b speed
c time
d velocity

Explanation:

Velocity is the rate of change of displacement, and acceleration is the rate of change of velocity. So displacement relates to velocity as velocity relates to acceleration (since \( v=\frac{\Delta d}{\Delta t} \), \( a = \frac{\Delta v}{\Delta t} \)).

Answer:

D. velocity
