Let's pretend that gravity stops. What would change?
Gravity is a pull you can not see. It makes things fall.
It keeps you on the ground. Without it, nothing would hold you.
Throw a ball up. Gravity pulls it back down.
With no gravity, nothing would pull the ball back down.
Gravity holds down the air we breathe. Earth keeps its air.
The Moon pulls the seas. That makes tides go up and down.
Gravity keeps the Moon going around Earth.
The Sun's gravity keeps Earth going around it.
It keeps Earth a good distance for light and warmth.
