Acceleration is defined as the rate of change of which quantity?
AThe velocity
BThe displacement
CThe distance
DThe elapsed time
Answer & Solution
Correct answer: A. The velocity
1. The summary states plainly what acceleration measures.
2. Acceleration tracks how fast velocity itself is changing, not how fast position is changing.
3. Because velocity is in m/s and acceleration divides that by more seconds, its unit is m/s squared.
