What is the role that gravity played in the formation of planets stars and solar systems and in determining their motions?
There is no doubt that planets, stars, and solar systems could not ever have formed without gravity. All of these astronomical objects condensed out of clouds of interstellar gas and dust, under the influence of gravity. It is also true that planets orbit stars only because of the gravitational attraction of those stars.

What controls the motions of the planets?
The motions of the planets are primarily controlled by gravity, which is the force of attraction between all masses in the universe. In our solar system, the Sun's gravitational pull governs the orbits and movements of the planets. The precise motions of the planets are also influenced by their initial velocities and the conservation of angular momentum.
What affect does gravity have on all matter in the universe?
Because of the existence of 'gravity', there are a pair of equal forces between every two specks of mass in the universe. Greater masses and smaller separations result in greater forces. These simple facts lead to the formation of galaxies, stars, and planets, and to virtually all of the motions we see, including orbits.
What is the force that causes the formation of the solar system?
The force that causes the formation of the solar system is primarily gravity. Gravity pulls particles and gases together, forming a spinning disk that eventually condenses into the Sun and planets. Other forces such as electromagnetic and nuclear forces also play a role in the formation process.
What role does gravity play in the formation of the stars and planets?
Gravity is the fundamental force that drives the formation of stars and planets by pulling together gas and dust in space. As these materials collapse under their own gravitational attraction, they form denser regions that eventually lead to the birth of stars. In the surrounding disk of material, gravity causes particles to coalesce and form larger bodies, eventually leading to the creation of planets. Thus, gravity is essential in shaping the structure and evolution of solar systems.
How does gravity affect all planets?
Gravity is the fundamental force that governs the motion of planets within a solar system. It acts as the attractive force between a planet and the star it orbits, keeping the planets in their elliptical paths. Additionally, gravity also influences the formation and structure of planets, contributing to their spherical shape and affecting their atmospheres and surface conditions. Overall, gravity is essential for maintaining the stability and dynamics of planetary systems.

Why do planets have circular and elliptical motions in the solar system?
The scientific explanation lies in Kepler's laws of planetary motions, which were discovered by Newton to be linked with the law of gravity. All the planets have elliptical orbits, and many of those are close being circular.
Newton applied his laws of motion to the problem of the motions of the planets. he assumed that it was gravity that held them into their orbits. true or false?
true
What force determines the motions of planets and other objects in the solar system?
The primary force that determines the motions of planets and other objects in the solar system is gravity. This force, described by Newton's law of universal gravitation, causes celestial bodies to attract one another, leading to the orbits of planets around the Sun and the moons around their respective planets. Additionally, Einstein's theory of general relativity refines our understanding of gravity, illustrating how massive objects warp spacetime, further influencing these motions.

What was gravity s role in the formation of the universe?
gravity clumped stars together, created planets and stopped everything from moving at the speed of light
Why is gravity vital?
Gravity is vital because it keeps objects grounded on Earth and helps to maintain the structure of the universe. It plays a crucial role in the formation of stars, planets, and galaxies. Without gravity, life as we know it would not exist.
What role did gravity play in the formation of the planets?
Gravity, of course has a central role in formation of planets. It's believed that the planets origin can be traced to the debris swirling around a young star. The term used for coming together of particles or bodies and joining together is 'accretion'. Gravity is the reason behind accretion . Small debris join together due to accretion and this accretion occurs further to give rise to larger and larger bodies like planets . Without gravity, this could never have occurred.
What are the two fundemental forces and how do they have an impact on the universe?
The two fundamental forces are gravity and electromagnetism. Gravity is responsible for the attraction between objects with mass, like planets and stars, determining their motions and structures. Electromagnetism governs the interactions between electrically charged particles, such as holding atoms together in molecules and determining the behavior of light. These forces play a crucial role in shaping the universe at both cosmic and atomic scales.
What is the force that causes the formation of the solar system?
The force that causes the formation of the solar system is primarily gravity. Gravity pulls particles and gases together, forming a spinning disk that eventually condenses into the Sun and planets. Other forces such as electromagnetic and nuclear forces also play a role in the formation process.
What is the only planet that is not spherical in shape?
All planets are 'round' because of gravity. With the formation of the Solar System, gravity gathered gas and dust into clumps which became larger and eventually planets. The collision of these pieces caused planets to become hot and molten and gravity pulled the molten material towards the planet's centre in the shape of a sphere. The planets cooled and remained spherical
Where do the planets get gravity?
Planets have gravity because they have mass.
