The conservation of angular momentum slows down a cloud's collapse by causing it to spin faster as it shrinks in size. This increased spin creates a centrifugal force that counteracts the force of gravity, helping to stabilize the cloud and prevent it from collapsing too quickly.

What causes planets to spin on their axes?
Planets spin on their axes due to the conservation of angular momentum, which is a fundamental principle in physics. As planets formed from rotating clouds of gas and dust in space, their rotation continued as they condensed and solidified. This spinning motion is what causes planets to rotate on their axes.
What do stars start out as in the process of their formation and evolution?
Stars start out as clouds of gas and dust in space. Through the process of gravitational collapse, these clouds condense and heat up, eventually forming a protostar. As the protostar continues to accumulate mass, nuclear fusion reactions begin in its core, leading to the birth of a star.
How do ice clouds in interstellar space contribute to the formation of new stars and planets?
Ice clouds in interstellar space play a crucial role in the formation of new stars and planets by providing the raw materials needed for the process. These ice clouds contain elements and molecules that can clump together under the force of gravity, eventually forming dense cores that collapse and give rise to new stars and planetary systems.
What are the different layers of clouds in the Earth's atmosphere?
The different layers of clouds in the Earth's atmosphere are classified into three main types: high clouds, middle clouds, and low clouds. High clouds are found at altitudes of 20,000 to 40,000 feet and include cirrus, cirrostratus, and cirrocumulus clouds. Middle clouds are located between 6,500 to 20,000 feet and consist of altocumulus and altostratus clouds. Low clouds are found below 6,500 feet and include stratus, stratocumulus, and nimbostratus clouds.
What are the straight line clouds called?
The straight line clouds are called "cirrus clouds."
What is the physical significance of orbital angular momentum?
Orbital angular momentum refers to the rotational motion of a particle around a fixed point. It is important in quantum mechanics as it quantizes the angular momentum associated with the motion of an electron around the nucleus in an atom. The magnitude and direction of orbital angular momentum affect the energy levels and the spatial distribution of electron clouds in atoms.
What types of protogalactic clouds is most likely to form an elliptical galaxy?
Protogalactic clouds that have a high angular momentum and a significant amount of gas and dust are more likely to form an elliptical galaxy. These clouds experience rapid, chaotic collapse and undergo turbulent mixing, leading to the formation of a dynamically relaxed and spheroidal galaxy like an elliptical. Moreover, a low rate of ongoing star formation and a lack of well-defined spiral structure are characteristics of elliptical galaxies, which can be traced back to the properties of the protogalactic clouds.
Why does the world pivot on its axis?
The world spins around because of the way the solar system was formed as a spinning cloud of matter. This then it began to collapse in on itself as it did this the heat at the centre became so great that the sun ignited and pushed out all the matter which then formed the planets, still spinning because of the energy from the explosion as the sun ignited.Supplement 2 As far as the planets are concerned, they would have had some net rotational momentum, the residual of all the components that made the planet.This rotational energy cannot be destroyed - it however might be cancelled out by opposite-spin material.BUT back to the question. The Earth carries the residual net spin from its assembly from space debris.Answer:The rotation comes about from the conservation of angular momentum. The formula for angular momentum is:L=mwr2m is the mass,w is the angular velocity in radians per second, andr is the radius of the circular motion.Due to conservation of angular momentum, as the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). As a consequence the parts of the planet closer to the primary (the Sun) must rotate faster than the parts furthest from the Sun. This causes the spin.This all relates to the fact that planetary and stellar systems are born from the collapse of dense interstellar clouds. As the clouds collapse even a small rotation is magnified by the contraction. If the clouds were not rotating (matter fell straight to the center of the system) there would be no planets.
What causes planets to spin on their axes?
Planets spin on their axes due to the conservation of angular momentum, which is a fundamental principle in physics. As planets formed from rotating clouds of gas and dust in space, their rotation continued as they condensed and solidified. This spinning motion is what causes planets to rotate on their axes.
Why planet rotation?
Stars and planets form in the collapse of huge clouds of interstellar gas and dust. The material in these clouds is in constant motion, and the clouds themselves are in motion, orbiting in the aggregate gravity of the galaxy. As a result of this movement, the cloud will most likely have some slight rotation as seen from a point near its center. This rotation can be described as angular momentum, a conserved measure of its motion that cannot change. Conservation of angular momentum explains why an ice skater spins more rapidly as she pulls her arms in. As her arms come closer to her axis of rotation, her speed increases and her angular momentum remains the same. Similarly, her rotation slows when she extends her arms at the conclusion of the spin.In our solar system, the giant gas planets (Jupiter, Saturn, Uranus, and Neptune) spin more rapidly on their axes than the inner planets do and possess most of the system's angular momentum. The sun itself rotates slowly, only once a month. The planets all revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus. These differences are believed to stem from collisions that occurred late in the planets' formation. (A similar collision is believed to have led to the formation of our moon.)Planets rotates beacos the sun tells them to
Size and shape of an electron cloud are most closely related to the electron's?
Size and shape of an electron cloud are most closely related to the electron's energy level and angular momentum. Electrons with higher energy levels tend to have larger electron clouds, while the shape is determined by the angular momentum quantum number.
Step by step of nebular hypothesis?
1) The solar nebula collapses; 2) The Spinning Nebula Flattens; 3) Condensation of Protosun and Protoplanets; 4) Massive expanding gas clouds; 5) Planetesimals collided and grew with other bodies; and 6) Nebulous clouds form.

How were stars formed in the clouds?
The prevailing view is that stars form from the gravitational collapse of immense clouds of gas and dust in outer space.
What caused the clouds to collapse?
Clouds don't really collapse but they do 'fall' from the sky as rain. You see clouds are made from water vapour that evaporate from the sea forming clouds and think how do they fall the fall by rain the water vapour creates water droplets and it's too heavy so they fall by rain
Interstellar gas clouds may collapse to form stars if they?
if they are massive enough and have sufficient gravitational force to overcome pressure forces and begin the process of nuclear fusion, which powers stars. This collapse is triggered by disturbances such as shock waves from supernovae or gravitational interactions with other clouds.
Why do all planets and moons spin?
The reason is tied to the origins of the Solar System as a primordial Sun surrounded by initially randomly swirling clouds of dust and gas. Pulled towards the Sun by gravity, these clouds became denser, with internal collisions leading to a preferred direction of motion. Like water spiralling round a plughole, the collapsing clouds swirled in this direction at an ever-faster rate, eventually becoming dense enough to collapse under their own gravity and form spinning planets and moons. The one exception is Saturn's moon Hyperion, which seems to have undergone a very violent impact, turning it into a potato-shaped rock that tumbles chaotically through space. RM
