Gravity and friction
Objects move according to their net force, or the total amount of force acting on them. Balanced forces are just that, balanced. An object with balanced forces will not move because the opposing forces will cancel each other out. However, if there are unbalanced forces, the object will move in accordance with the force that is greater. When moving though, there is always friction. Whether you be underwater, on the ground, or in the air there is always friction on the Earth. (Besides vacuums, of course.) Force is equal to mass x acceleration. With that you can find the forces of the object if you know its mass and acceleration.
Forces act by means of exchange particles. There are four basic forces (which operate in numerous different ways) each having its own exchange particle. The force of gravity is conveyed by the graviton. The electromagnetic force is conveyed by the photon. The two nuclear forces are conveyed by mesons. A particle that is exerting a force will emit an exchange particle, and a particle which is experiencing a force will absorb that exchange particle. That is essentially how it works, on a subatomic level. There are also mathematical equations which describe the forces, for example, the electromagnetic force is described by Coulomb's Law.
i knowwere you live ill punch you in the face
No; gravity will continue acting on your body. If there was no force acting on your body while in space (let's say an orbiting satellite), the satellite would fly out of Earth's orbit and just wander off forever, but that doesn't happen - so gravity has to be acting on the satellite and your body as well!
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
This is the geologic principle of uniformitarianism.
All objects on earth have the force of Gravity acting on them.
Gravity and air resistance.
98.07 newtons on earth.
Magnetism, friction, and reaction forces in general.
Yes. But how do u know?
That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.

momentum i think
If something is moving, no force is required for that something to continue moving. That doesn't mean there are no forces acting on Earth; for example, the Sun attracts Earth towards it. But that's not what keeps the Earth moving.
Answer #1:The ratio of forces acting on 2 charges 1 and 5 can be 11 if you include theother external factors.===============================Answer #2:The forces on each one due to the other one are equal, regardless of thesize of either charge. That is, the ratio of the forces is always 1 to 1 .Just like with gravity. The force you exert on the Earth is exactly the same asthe force the Earth exerts on you. Your weight on Earth and the Earth's weighton you are equal.
-- the gravitational attraction between the football and the Earth, acting vertically downward; -- the normal force of the ground or the shelf under the football, acting vertically upward. These two forces are precisely equal and opposite. If they're weren't, then the football would be accelerating vertically, not at rest.
