The video explains why planets orbit the sun in a flat plane, tracing back to the solar system's formation from a spinning gas cloud. This process, driven by gravity and angular momentum, led to a disk shape where planets formed. Most planets orbit in the same plane, but some objects have inclined orbits due to gravitational influences from larger planets. This phenomenon is common in other star systems as well.

Why do the planets in our solar system orbit in a flat plane?

• Due to the solar system forming from a spinning cloud of gas and dust

• Because of the influence of nearby stars

• Because of the gravitational pull of the sun

• To save space in the universe

What principle explains the increase in spin as the cloud of gas and dust collapsed?

• Conservation of linear momentum

• Conservation of energy

• Conservation of mass

• Conservation of angular momentum

What event is most likely to have triggered the collapse of the gas and dust cloud?

• The formation of a black hole

• A nearby supernova

• A collision with another galaxy

• The explosion of a nearby planet

How do we know that disks form around young stars?

• Through computer simulations

• By studying ancient texts

• By observing them in our galaxy

• Through mathematical models

Why do some objects in the solar system have inclined orbits?

• They are too small to have stable orbits

• They are made of different materials

• They were influenced by the gravitational pull of Jupiter and Neptune

• They were formed in a different solar system
