No.
The weight of rocks can vary depending on the size and type of rock. On average, a small rock may weigh around 100 grams, so 10 rocks could weigh about 1 kilogram (1000 grams). However, for more accurate measurement, each rock would need to be weighed individually.
the same
yes
of course not
To be more specific than the previous answer, kilogram is a unit of mass. Weight is related to mass by Newton's second law of motion, which relates to us that force (weight) is equal to mass times acceleration (gravity). Provided that the objects in question are weighed at the same location, their weights will be identical, as a) their mass is the same and b) their acceleration is the same, and so the equation F = M x A (force equals mass times acceleration) indicates that the force (weights) are the same.
The surface gravity of Neptune is thought to be about 1.14 times the gravity on Earth, so 100 kg on Earth would weigh about 114 kg on Neptune--except that Neptune is a gas planet and has no solid surface on which the 100kg rock could be weighed.
it is the same weigh.
yes
That depends entirely upon how large the rock is. You'd have to weigh each individual rock to see for certain.
Kilogram or ton.
Yes. Kilogram is the unit of mass.
The weight of a rock can vary greatly depending on its size and composition. On average, a small rock may weigh a few ounces to a pound, while larger rocks can weigh several pounds or even more. If you have a specific rock in mind, it would be best to weigh it using a scale.
