The sun is just a huge ball of hydrogen and helium. The heat created on the sun is from billions of hydrogen atoms smelting together to helium atoms. All these atoms are held together by the gravity.
The force that holds the sun together is gravity. Gravity is the force of attraction between all objects with mass, and it keeps the sun's mass from expanding outward. This gravitational force is what keeps the sun's core hot and dense enough for nuclear fusion to occur, which is what powers the sun's energy output.
The Sun's gravity holds the solar system together.
The force that holds the nucleus together is the strong nuclear force. This force is mediated by particles called gluons, and it is responsible for binding protons and neutrons together in the nucleus.
kinatic force
The strong force holds the nucleus together against the repulsion between the electric charges of the protons.
The strong atomic force holds protons (and neutrons) together in the nucleus.
Gravity, the force of attraction between all masses in the universe, is the inward force that holds a star together.
the force of attraction that holds atoms together is a chemical bond
The force that holds protons and neutrons together in an atomic nucleus is called the strong nuclear force.
chemical bond holds together the atoms in a substance
The residual strong force. The strong force (or color force) is what holds quarks together to form protons and neutrons. The residual strong force then holds the protons and neutrons together in the nucleus.
