Which universal force can repel as well as attract?
The gravitational force is proportional to the product of the two masses involved. The product is always positive, since mass is always positive. The electrical force is proportional to the product of the two charges involved. The product can be positive or negative, since either charge can be positive or negative.
Why is gravity a pull?
The forces of gravity are always 'attractive' ... pulling masses together.According to the math that describes the process, the forces of gravity wouldpush two objects apart if one of them were composed of 'negative mass' ...just like one positive electrical charge and one negative charge repel eachother. So far, however, negative mass has never been observed, even in thelaboratory, and we don't see anything going on anywhere in the observableuniverse where it appears as if objects are repelling each other.
Is the sum of two negative integers always negative?
Yes, the sum of two negative integers is always negative.
Does forces always work in pairs?
