The force to keep us and nearly everything else on the ground is GRAVITY.
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.
Gravity
The force of gravity keep a bycicle on the ground.
Gravity keeps us on the ground because it is a natural force that pulls objects towards each other with a force proportional to their mass. In the case of Earth, gravity pulls everything towards its center, keeping us firmly planted on the ground.
The upward normal force from the ground pushes against gravity to keep you from sinking into solid ground when you stand. The normal force is caused by the atoms in the ground that resist being compressed by your weight, resulting in a balanced force keeping you upright.
The force of gravity is what keeps us on the ground.

yes
Gravitational pull. It is pulling us towards the centre of the Earth. It is not visible . In space there is no gravitational force so we fly in space
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.
Gravity pulls objects toward the center of the Earth. However, the ground provides an upward force called "normal force" that counteracts gravity, keeping us from being squashed into the ground. This balance between gravity and the normal force allows us to stand and move on the Earth's surface.
Things have weight due to the gravitational force exerted by the Earth on them. The weight of an object is the measure of the gravitational force acting on it, pulling it towards the Earth's center. This force is directly proportional to the mass of the object.
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 !
