Gravity and Fusion.
The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
The two forces that result in the orbit of a planet are gravitational force, which pulls the planet towards the center of the star it is orbiting, and the planet's tangential velocity, which keeps it moving in a curved path around the star. These two forces are perfectly balanced in a stable orbit.
Objects are not made of forces. A star is made of hydrogen, helium and, later in its life, heavier elements.
The outward forces on a star, primarily generated by nuclear fusion in its core, counterbalance the inward gravitational forces trying to collapse the star. The balance between these forces determines the star's size and stability; if the outward pressure increases (e.g., from increased fusion due to higher core temperatures), the star expands. Conversely, if the inward gravitational force becomes stronger (e.g., from a depletion of nuclear fuel), the star contracts. Thus, the interplay of these forces is crucial in defining a star's size and evolutionary state.
A star that is gravitationally bound to another star can either be part of a binary star system, where two stars orbit around a common center of mass, or be part of a star cluster, where multiple stars are held together by gravitational forces within a common region of space.
It is possible but unlikely because the competing gravitational forces from two or more stars are very likely to make it impossible for any planet to settle into a stable orbit.

Gravity and radiation pressure.
In a star, the force of gravity is trying to collapse the star inward, while the pressure from nuclear fusion in the core creates an outward force, resisting the gravitational collapse. These two forces are balanced in a stable star, leading to a state of equilibrium.
The two competing fundamental forces inside the nucleus of an atom are the strong nuclear force, which holds protons and neutrons together, and the electromagnetic force, which causes positive charges (protons) to repel each other. The strong nuclear force overcomes the electromagnetic force at close distances, keeping the nucleus stable.
Gravity pushes and pulls on a star, balancing it out so it doesn't explode.
Inside a star, there are two opposing forces at play: gravity tries to pull the stellar material inward, compressing it, while the force of nuclear fusion in the star's core pushes outward, generating energy and counteracting gravity to maintain the star's stability. These forces must balance each other for the star to remain in a state of equilibrium.

The competing of small and large state
Constructive forces build up landforms by depositing materials, while destructive forces break down landforms by erosion or weathering. They are considered competing because constructive forces are constantly working to create new landforms, while destructive forces aim to break down existing landforms. The balance between these forces determines the overall shape of the Earth's surface.
