Gravity and the upward force of the surface the object is resting on.
An object that weighs 100 newtons on or near the Earth's surface has about 10.197 kilograms of mass. It doesn't matter whether it's moving or at rest, or what its speed is. Its motion has no effect on its mass or weight.
An object can be at rest relative to a second object whilst in motion relative to a third object.For example, if you sit still then relative to the Earth you are at rest. However the Earth is both spinning on its axis and travelling around the Sun, so relative to an observer in space you are in motion. Einstein showed us that all such concepts are relative.

The force of gravity is a force and can be described in terms of any of the usual units of force.However, since the force of gravity on an object depends on the object's mass, we need a wayto describe the gravitational 'field' without knowing the mass of each object. So we describethe gravity, for example on the surface of the Earth, in terms of the acceleration of gravity there,because any object near the surface but falling the rest of the way will have the same accelerationregardless of its mass.

The Earth's gravity stops the object from floating when at rest.
Friction.

There are lots of ifs in this question and answer. If the 100 pound Earth object could rest on the outer surface of Jupiter the answer would be 250 pounds. But, Jupiter is a gas planet. That is, Jupiter is primarily made of gas and liquid. So, the object could not rest on the outer surface. There may be a solid surface near it's center but no one knows. Jupiter is 318 times as heavy as Earth so if Jupiter were solid and the size of Earth the object would weigh 318 times a much or 31,800 pounds. But, it is much larger than Earth so the outer surface is much farther from the center. The farther away the object is from the center the less the object will weigh.
Will you accept heat? Or would you prefer the potential energy it has before falling down a well? It's all relative.
There CAN be, as long as the force is being counterd by an equal and opposite force.
That depends what data you are given. Close to the Earth's surface, such an object will accelerate at 9.8 meters/second2, so if it starts from rest, after "n" seconds, it will have a speed of "9.8n" meters/second.
Radiant energy will either be reflected or absorbed by a surface. The usual rule regarding this reflection depends on the color of the object and the color of the light. For example, a red object only reflects red light, and absorbs the rest. A blue object only reflects blue light, and absorbs the rest. This goes for all of the colors. When radiant energy is absorbed, the object will heat up. Hope this helps!
The rest of the world are experiencing worse price rises then the US.
No. The surface of the earth is held to the planet by gravity. However parts of the surface move relative one to another - this is called plate tectonics.
