The energy produced by the star, which manifests itself as heat.
The three types of pressure that can push against the inward force of gravity are thermal pressure (due to high temperatures), radiation pressure (from electromagnetic radiation), and degeneracy pressure (resulting from quantum effects in dense matter).
Hydrostatic pressure is the pressure exerted by a fluid at equilibrium due to the force of gravity. It is determined by the density of the fluid, the acceleration due to gravity, and the depth of the fluid. The pressure increases with depth in a fluid column.
Pressure= Force/Area Pressure of a Liquid is density times gravity times height
The four factors are pressure gradiant force, coriolis force, friction force and gravity. Pressure gradient force move airs of higher pressure to lower pressure. Coriolis force prevents anything from moving in a straight line to earths oblate sphere. Friction rides the wind and without it air would travel parellel. Gravity because the power of gravity pulls air down.
While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star.
A force that resists motion is inertia.
The force that resists gravity is called normal force. It is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

air pressure
The fundamental force that contributes to pressure in both water and the atmosphere is gravity. Gravity causes the weight of the water or air above a certain point to exert a force downwards, which leads to pressure at that point.
pressure
F(gravity) pulls a movable object toward the center of mass (generally the Earth). F(friction) resists F(gravity) when the object is scraping against something that is solidly attached to the mass (Earth).
The mechanical force that resists gravity in the lifting of an object is known as the normal force. This force is exerted by a surface in contact with the object and acts perpendicular to the surface to support the weight of the object.
The pedals could be one but none thing really resists a pulling force because gravity is a pulling force that acts on everything that has weight.
The pressure of gravity on a surface is(total force of gravity on the surface) divided by (area of the surface)
It is balanced by radiation pressure, and gas pressure.
