Object

How much mass does an object have to obtain for it to have a gravitational force?
Q. As everyone knows the more mass an object has the more its gravitational force. But i was wondering what the minimum amount of mass an object has to have for it to have a gravitational force. For example the average human weighs about 150lbs. Weight is like mass. So if a human can have this much weight, and not a gravitational pull, then that means that there must be a certain mass, and when this mass is obtained, that an object has to reach to have a gravitational force.

A. Any amount of mass, no matter how small. The gravitational pull of a 100-kilogram (220.46 pounds) man to another of the same weight standing next to him is 0.00010678848 Newtons, which converts to 0.0003841 ounces. Far too little for a human to feel, but present and measurable. The same units are used for mass and for weight and cause no end to confusion. Mass is not weight. .

What happens when an object on a circular track is accelerated faster than the speed of light? Time travel?
Q. What happens when an object on a circular track is accelerated faster than the speed of light? Time travel? Will the object run into itself?

What's the difference between an object complement and a direct object?
Q. Pls look at this sentence:"We ask him to sign this bill." Herein, "to sign this bill" is said to be the direct object of the verb "ask"; However, why can't it be considered as an object complement. As it is said "When the word follows the direct object and it tells what the direct object has become, it is the object complement." Why can't it be thought in this way: He has been forced to sign the bill, thus, the state of him has been changed. In this way, can "to sign the bill" be considered as an object complement?

A. Your reasoning is correct except you have a pronoun as object in one case and a phrase in the other. We ask him to sign the bill. Him as opposed to anyose else. When you say "We ask to sign the bill" it means something different because, as you have stated, that action is the object of "ask". You could ask to have another coffee.But the important difference is that "he" is not asked to sign the bill. To ask to sign the bill and to ask him to sign the bill are two different objects of "asking" and two completely different sentences.
