The force to keep us and nearly everything else on the ground is GRAVITY.
Space pushes down on us
The force of gravity keep a bycicle on the ground.
Forces essentially cause everything in the universe. The combination of magnetic, electric, and gravitational forces explain how stars are born and die as well as how you can move.
The US Military is divided into 4 branches: the US Army: the largest of the branches, used for sustained military operations the US Air Force: to control the skies and keep our troops brom being bombed and flying transport and resupply missions. the US Marine Corps: our large, force in readiness, able to mobilize faster than the Army and strike first. the US Navy: to control the sea lanes to keep our troops resupplied and also as the force to mount a "show of force" in areas far from the US The US Military is divided into 4 branches: the US Army: the largest of the branches, used for sustained military operations the US Air Force: to control the skies and keep our troops brom being bombed and flying transport and resupply missions. the US Marine Corps: our large, force in readiness, able to mobilize faster than the Army and strike first. the US Navy: to control the sea lanes to keep our troops resupplied and also as the force to mount a "show of force" in areas far from the US
Gravity.
21st century air force does, but not during the Viet War. The USAF ground troops are special ops personnel.

The force of gravity is what keeps us on the ground.
it spins and we stay stil because of the gravity force to keep us staying on the ground thats how

yes
Gravitational force is important to us as well as air close to the ground.
The force that keep's us (or you) is the gravity.
the stuff that keeps us on the ground :)
While pushing we actually apply force on the ground which is opposed by frictional force acting on our feet.The ground now applies a normal reaction force on us which we apply on the body to be pushed.
while gravitional force pulls us down , the opposing force from the ground pushes us upward and the two opposite forces cancel each other out , which create inertia mean NO MOTION !
the up thrust force on us is the ground stopping us from flying straight to the core.It acts against gravity.
