the test is due today please help T0T
Gravity helped smaller bits combine to a larger mass, which then attracted more bits to form the planets
Certainly! Here's a step-by-step explanation of how gravity influenced the formation of the solar system with the planets orbiting the sun:
1. Initially, the solar system began as a giant molecular cloud, which is a vast region in space consisting of gas and dust particles.
2. Gravity played a pivotal role in the collapse of this molecular cloud. As the cloud contracted due to its own gravity, it began to spin slowly.
3. As the cloud continued to collapse, the gravitational force caused it to spin faster and flatten into a spinning disk shape. This spinning disk is known as the protoplanetary disk.
4. The center of the spinning disk became denser and hotter, eventually forming the sun. The force of gravity brought gas and dust particles closer together, allowing them to merge and form the star at the center of the system.
5. Within the protoplanetary disk, regions of higher density began to form due to the gravitational attraction between particles. These regions are called protoplanetary embryos or planetesimals.
6. Over time, the protoplanetary embryos continued to grow, attracting more gas and dust and increasing their mass. The gravity of these growing bodies influenced the surrounding material, causing them to accrete more mass and grow further.
7. As the protoplanetary embryos reached a critical mass, their gravity became strong enough to attract and hold onto gas, forming gas giant planets like Jupiter and Saturn.
8. In the inner regions of the protoplanetary disk, where it was hotter, the rocky and metallic materials condensed to form terrestrial planets like Earth, Mars, Venus, and Mercury.
9. As the process continued, the gas and dust in the disk were eventually swept away or incorporated into the newly formed planets.
10. The final result was a stable solar system, where the planets orbit the sun in elliptical paths due to the gravitational pull between them and the sun.

Certainly! Gravity played a significant role in the formation of the solar system and the way planets orbit the Sun. Here's an explanation of how gravity influenced this process.
1. Initial Nebula: The solar system began as a giant cloud of gas and dust called a nebula. Gravity acted as the initial force that caused this nebula to collapse inward due to its own gravitational attraction.
2. Proto-Sun Formation: As the nebula contracted, it started to spin faster due to the conservation of angular momentum. The central region became denser and eventually formed a protostar, which became the Sun. Gravity played a crucial role in pulling matter together to create the Sun.
3. Accretion of Planetesimals: As the protostar formed, remaining gas and dust began to orbit it in a disk-shaped structure called the protoplanetary disk. Small particles collided and gradually stuck together due to their mutual gravitational attraction, forming planetesimals (small planetary building blocks).
4. Planet Formation: Over time, planetesimals grew larger through further collisions, forming protoplanets. Gravity caused these protoplanets to attract more material, gradually increasing their mass. Ultimately, they evolved into the planets we know today, such as Mercury, Venus, Earth, Mars, etc.
5. Orbits and Stability: Each planet formed in its own orbit around the Sun due to the gravitational forces acting between the protoplanetary disk and the forming planet. The planets' orbits stabilized as they cleared their orbital paths of remaining debris, thanks to gravitational interactions.
In summary, gravity played a significant role throughout the process of solar system formation. It caused the initial collapse of the nebula, facilitated the formation of the Sun, enabled the accretion of planetesimals, and shaped the orbits of the planets around the Sun. It's essential to understand that gravity is a fundamental force in the universe, governing the dynamics and movement of celestial bodies.
