Why g=9.8 m/s2| Forces | Gravity | Tamil | Nothing But Science?

g = 9.8 m/s² means that when something falls, it speeds up by about 9.8 meters every second, because of gravity.

Imagine you drop your favorite toy from the top of a tall chair, poof, it starts falling! Gravity is like an invisible hand pushing it down toward the floor. Now, this number 9.8 might look complicated, but think of it as how hard Earth pulls things to itself.

Gravity is like a strong hug from Earth, it grabs everything and brings it down. Even you! When you jump up, Earth pulls you back down. That’s why you always land on the floor.

Now, 9.8 m/s² means that every second something is falling, it goes faster by almost 10 meters (like running from one end of a classroom to the other). So if your toy drops for 2 seconds, it would be going about 20 meters per second, that’s like zooming past your teacher in no time!

Earth's gravity is strong because it's big and heavy. But don’t worry, we use 9.8 as a number to help us figure out how fast things fall, just like you count steps when you walk!
