in which situation you exert more force downward, standing or lying horizantilly?
Gravitation
The force of gravity keep a bycicle on the ground.
The force to keep us and nearly everything else on the ground is GRAVITY.
Gravity.
21st century air force does, but not during the Viet War. The USAF ground troops are special ops personnel.
Yes, a pile of soil sitting on the ground exerts force on the ground beneath it. The soil has mass, and gravity pulls it down on the whatever is under it. A red ant standing atop the pile of soil exerts an extra force on it, to continue the figure.
Yes, anything on the surface of the planet which is at rest exerts a force on the ground and the ground exerts a force on it.

150 lbs. In order for the floor to support you it must resist an equal force.

Your feet exert a force on the ground so in return the ground exerts a force on your feet.
When you stand still . . . The sole of your shoe exerts a downward force equal to your weight against the ground. The ground exerts an upward force equal to your weight against the sole of your shoe. The net force where the sole of your shoe meets the ground is zero, which is the reason that your shoe doesn't accelerate vertically.

Well, according to Newton's third law, every action has an equal and opposite reaction, so the ground would exert 3000 Newtons back on the moose.
