What if your weight is a force acting on the rock what force acts on you?
If you sit on a rock with a downward force of 'W' pounds, then the rock exerts an upward force of 'W' pounds on your derriere. We know that the sum of the forces on the seat of your pants must be zero. Otherwise the pants would be accelerating, either up or down.
What exerts force?
A force is a push or pull acting upon an object as a result of its interaction with another object. ie myself against a rock or my trying to pull the rock
Given that a helium balloon weighs more in a vacuum chamber on earth than in the earth's atmosphere would a rock weigh more in a vacuum chamber on earth than in the earth's atmosphere?
Yes. Any material object in a fluid is "buoyed" up by a force equal to the weight of the fluid it displaces.In air, the weight of the rock is reduced by an amount equal to the weight of the air that would otherwise occupy the rock's volume if the rock were not there.
What is a reaction force and formula?
The idea of a reaction force comes from Newton's third law; "If object A exerts a force on object B ,then object B will exert an equal but opposite force back on A". In many problems some of the forces are considered as the "initiating" force or the applied force. When you consider a force as being applied, like a bulldoser pushing a rock, then the force which must act back , the rock pushing back on the doser, is called the reaction force. Sometimes you don't really have an initiating force but it still convienient to think of one force as the force of interest and the back force as the reaction force. There is no single formula for reaction force since it can apply to any force. For example, the earth attracts you with a force mg (your weight), then you can think of the reaction force as you attract the earth with a force -mg; equal but opposite.
Is the mass of an object the force of gravity acting upon it?
Weight is not a force. Weight is a phenomenon associated with a mass in a gravimetric field. It's actually the acceleration of a mass acted on by gravity, which is a force. A 100-pound rock would weigh nothing in deep space. It would be weightless. But the rock weighs 100 pounds on earth because of (mostly) the mass of the earth and also (just a tiny bit) because of the mass of the rock.

What is the weight of a rock that has the mass of 7 kg?
The rock's weight or force in Newtons is 68.65
Buoyant force of a rock submerged in water compared to the weight of the water displaced by the rock?
The buoyant force is equal to the weight of the displaced water.

If you drop a rock what is the force acting on it?
Gravitaional force is the force pulling on it from the Earth.

When you use a crowbar to lift a heavy rock which force is bigger the weight of the rock or the force applied to the end of crowbar?
the force, otherwise the rock would not move.
What force squeezes the rock in the Earth's crust?
Stress forces squeeze or pull the rock in the Earth's crust.
What force other than gravity is pushing on a rock when it sinks?
The "buoyant" force is acting on it, in the vertically upward direction. That force is equal to the weight of the water that would be in the volume of the rock if the rock weren't there.
When earth's force slants rock layers it is called?
tilting
