What does 9.8 mean in gravity?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The number 9.8 represents the rate of acceleration (in meters per second suared) that gravity causes on objects near Earth's surface. It means that for every second an object falls (ignoring air resistance), its velocity increases by 9.8 meters per second. After 1 second of falling, an object reaches 9.8 m/s; after 2 seconds, it's moving at 19.6 m/s; after 3 seconds, 29.4 m/s, and so on. This constant acceleration is why falling objects speed up continuously rather than falling at a steady speed.
