The term "Earth gravitational force" refers to the force that pulls objects towards the Earth. It's the reason things fall when you drop them. Gravity is a natural force that exists between any two objects with mass. The Earth's gravity is what gives weight to objects.
The Earth's gravitational force is pretty much the same everywhere near its surface. We call this standard gravity or acceleration due to gravity. It's about 9.8 meters per second squared. This means that for every second an object falls, its speed increases by 9.8 meters per second.
Gravity affects many things around us. It keeps the air and atmosphere around the Earth. It also causes the ocean tides to rise and fall. Without gravity, we would float away into space.
Understanding gravity is important in fields like physics and engineering. It helps scientists calculate how things move and how to build structures that can withstand gravitational forces. It's also important in astronomy to study how planets, moons, and satellites move in their orbits.
