Standard gravity

Gravity is a force that pulls things together. You can think of it like a big magnet that attracts everything around it. Standard gravity is a measure of how strong this magnet is.

When you jump off a chair, gravity pulls you back down to the ground. The force of gravity is what makes objects fall to the ground instead of floating up to the sky. So, standard gravity is how we measure the strength of this force. Scientists use a number called "g" to represent standard gravity.

The value of "g" is different depending on where you are on Earth. If you’re standing on the equator, "g" is weaker because the Earth is spinning and things get pulled to the sides. In other parts of the world, "g" can get stronger or weaker depending on how close or far you are from the center of the Earth.

In space, there is no standard gravity because there is no big object pulling everything together. Astronauts have to use special equipment to simulate gravity so they can move around and do things like they would on Earth.

So, in short, standard gravity is a way of measuring how strong the force of gravity is on Earth. It's what makes things fall to the ground and keeps us all from floating off into space!
