That force is known as the "strong force", the "nuclear force", or the "residual strong force".
the nucleas
No. Gravity is an attractive force, meaning it acts to pull things together.
Gravity acts to pull objects together. That's called an "attractive" force, not a 'repulsive' one.

Friction
Gravity.
Gravity would be the most obvious answer. Does that help? If not, i can elaborate.
Gravity acts upon any objects in space.
The force that acts against gravity is the buoyant force.
An object is stationary until a force acts on it, then when a force acts on it it will keep going the same direction and speed forever, until another force acts on it.
I think it might be electrostatic force! This is the force that acts between the particles!
strong nuclear force which acts between all nucleons keeps them together
