A star is primarily affected by two opposing forces: gravitational force and radiation pressure. Gravitational force pulls the star's mass inward, trying to collapse it, while radiation pressure, generated by nuclear fusion reactions in the star's core, pushes outward. The balance between these forces determines the star's stability and lifecycle. If the balance is disrupted, it can lead to various evolutionary stages, including expansion into a red giant or collapse into a supernova.

What are two competing forces in a star?
The two competing forces in a star are gravity, which tries to collapse the star under its own weight, and nuclear fusion, which generates energy and causes the star to expand outward. These forces balance each other to maintain a stable, long-lived star.
What are the two forces acting on the particles inside a nebula that affect its balance and how do they affect particles?

How many opposing forces are there in a stable star?
In a stable star, there are primarily two opposing forces at play: gravitational force and radiation pressure. The gravitational force pulls matter inward, while radiation pressure, generated by nuclear fusion reactions in the star's core, pushes outward. These forces balance each other, allowing the star to maintain a stable state throughout most of its life cycle.
Two main forces in a star?
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.

What are the two forces that are in equilibrium in a star?
Hydrostatic and Equilibrium
What happens when two or more forces affect an object at the same time?
When two or more forces affect an object at the same time it creates a net force.
Four forces that effect a birds flight?
Weight and lift are two forces that affect a bird's flight. Two other forces are drag and thrust.
Two forces that can affect an object's velocity?
Gravity and friction.
What two things about forces are important when forces are combined?
The magnitude (size) AND the direction, of all the forces, all affect their combination.

What two forces affect acceleration?
The two forces that affect acceleration are net force and mass. Acceleration is directly proportional to the net force acting on an object and inversely proportional to the mass of the object.
What are two forces that affect us when you float?
Two forces that affect us when we float in water are buoyancy, which pushes us upwards due to the displacement of water, and gravity, which pulls us downwards. The interaction between these two forces determines our stability and position while floating.
Name the two forces that can affect an object's velocity?
friction and gravity
