Acceleration is measured in what SI unit?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. m/s2.
Acceleration, the rate of change of velocity with respect to time, is measured in meters per second squared (m/s²) in the International System of Units (SI). One meter per second squared represents an increase in velocity of one meter per second every second. This unit quantifies how quickly an object's velocity changes over time, whether it's speeding up, slowing down, or changing direction. It's a crucial concept in physics and is used extensively in mechanics, engineering, and everyday life.
