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 main forces that make up a star?
Objects are not made of forces. A star is made of hydrogen, helium and, later in its life, heavier elements.
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 main restroing forces for tides?
The two main restoring forces for tides are gravitational forces from the Moon and the Sun. These forces create bulges in the Earth's oceans, causing high and low tides as the Earth rotates within this gravitational field.
What are the two most abundant elements in a main sequenced star?
The two most abundant elements in a main sequence star are hydrogen and helium. Hydrogen is the primary element, composing about 75% of the star's mass, while helium makes up most of the remaining mass.
Which two factors determine the characteristics of a star?
The two main factors that determine the characteristics of a star are its mass and its age. The mass of a star determines its temperature, size, luminosity, and lifespan. A star's age affects its stage in its life cycle, such as whether it is a young, main-sequence star or an older red giant.
What force make a star?
All of the forces act to make a star. Gravity is the main force, which pulls everything together, and the other forces ignite the star.

What are the two forces that are in equilibrium in a star?
Hydrostatic and Equilibrium
What are the two main forces driving forces of the cycle?
Denudation and Volcanism.
What are the two main restroing forces for tides?
The two main restoring forces for tides are gravitational forces from the Moon and the Sun. These forces create bulges in the Earth's oceans, causing high and low tides as the Earth rotates within this gravitational field.
What were the two main forces acting on Felix Baumgartner when he jumped out of the capsule?
The two main forces acting on Felix Baumgartner when he jumped out of the capsule were gravity, pulling him downward towards the Earth, and air resistance (drag), which opposed his fall and slowed his acceleration.
What forces are opposing one another throughout the life of a star how do they influence the various stages in life cycle of a star?
In the life cycle of a star, the force of gravity tries to collapse the star inward, while the force of nuclear fusion pushes outward to provide energy and heat to counteract gravity. These opposing forces determine the balance between contraction and expansion that defines the different stages in a star's life cycle, such as main sequence, red giant, and supernova.
What two forces are working against each other in a star?
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.
What two internal forces are acting on a stable state star?
Gravity and radiation pressure.
What two forces are at work in a star?
The two main forces at work in a star are nuclear fusion, where hydrogen atoms combine to form helium and release energy, and gravity, which pulls inwards and tries to collapse the star. These forces are balanced in a stable star, maintaining its structure and energy output.
What are the two major forces that act on a star?
Gravity pushes and pulls on a star, balancing it out so it doesn't explode.
