Ask Astro Can planets be pear-shaped, or are they all spheres?.

At first, special relativity may not seem to have much to do with gravity, but it was an essential stepping stone for Einstein for understanding gravity. Moving clocks tick more slowly. Experiments during Einstein’s time had shown that the speed of light appeared to be constant. No matter how fast you try and catch up, light always appears to. Perhaps surprisingly, yes. Earth spins on its axis once every 24 hours (the definition of a day). Mars, which is smaller, spins slightly slower with a period of 1 day and 37 minutes. Mercury, the smallest of the rocky planets, has a rotational period of 58 days. Venus spins slower than all of them, with a period of 116 days. The faster the spin, the more unround it becomes. Then, when it cools and hardens, it retains that shape. If a molten planet starts off spinning faster, it would be less round and have a bigger bulge.

How fast would the Earth have to spin to cancel gravity at the equator.

The outer atmosphere and internal heat have created cloud bands and the Great Red Spot - a giant storm that has lasted more than 300 years. Jupiter also has three faint rings that surround the planet. Jupiter also spins faster than any other planet, taking a little under 10 hours to complete a turn on its axis, compared with 24 hours for Earth.

Why are planets round? - The Conversation.

The answer lies in the fact that planets are round, and so they have a lot of gravity too, which means they are pulled in all directions equally. The sun does not pull the planets in because they are round shapes with equal gravity. The planets do not move in a straight line, so the force of gravity from the sun is constantly changing. 1. The farther planets have a lot more mass, so they're likely to move a bit slower. 2. They are much farther away so the suns gravity is not as powerful as it would be if they were closer. 3. Its.

Why Jupiter spins fast, but not really fast - astrobites.

That means it spins nearly perfectly upright and so does not experience seasons as many other planets do. Moons. Moons. Mercury doesn't have moons. Rings. Rings. Mercury doesn't have rings. Formation. Formation. Mercury formed about 4.5 billion years ago when gravity pulled swirling gas and dust together to form this small planet nearest the Sun. This results in a limit for how fast an object can rotate and still keep itself together. If it rotates too fast, the outward acceleration felt by the elements in the body may be more than the force that keeps them bonded together, and if this happens, the body breaks up. Other than this, there is no real law concerning rotations. Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of reference), as opposed to the force experienced in.

Curious Kids: What makes the Earth spin on its axis every day?.

Centrifugal acceleration is ω 2 r, so in order to have a centrifugal acceleration of 1 / 2 g at the equator you will need ω = g / 2 r, giving ω = 0.000875 rad/s; the planet rotates about 12 times faster than Earth, completing a rotation in just a little under 2 hours. ( ω is the angular speed in rad/s, r is the radius of the planet, here.

How Do We Weigh Planets? - NASA Science for Kids.

Unless the spin is under constant acceleration then you seem to have got speed and acceleration all mixed up; the acceleration due to gravity should be thought of as a potential acceleration whilst a constant speed has no acceleration even in potential.. Edit to add/ The poles are only 43 km closer to Earths centre than the equator which equates to 0.03% off a perfect sphere, so any difference.

Gravity: A simple introduction - Explain that Stuff.

The Short Answer: To weigh a planet, scientists need to know two things: how long it takes objects to orbit the planet and how far away those objects are from the planet. The time it takes an object to orbit a planet depends on its distance from the planet and the planet's weight. In real life, we can't pick up a planet and put it on a scale.

Q & A: Gravity vs. Magnetism - Department of Physics.

As mentioned by one or two above, gravity is a perceived effect caused by curving space. Mass causes this curve, so mass causes gravity. Electro-magnetism has nothing at all to do with gravity, and the spin of the earth actually slightly reduces our perception of gravity since the spin is pushing us AWAY from the surface.

Planetary Physical Parameters - NASA.

Answer (1 of 5): Spinning of the earth (or a planet) does not affect the gravity, but spinning of a planet reduces the gravitational pull experienced by an object placed on the surface of that planet. The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to.

How does spin effect the force of gravity? askastronomy.

Here are some more cool planet spinning facts: All the planets have different day lengths. Mercury's day is about 59 Earth days, while Jupiter's day is only 10 Earth hours long.

Do all planets spin in the same direction? - Urban Astronomer.

In our solar system, Mercury and Venus are slowly spinning rocky planets; therefore, they are the most spherical of the Sun's worlds. Earth and Mars spin a little faster, so they are about 0.3. This takes the form of the equation: F_ {grav}=\frac {Gm_1m_2} {r^2} F grav = r2Gm1m2. where F grav is the gravitational force in newtons, m 1 and m 2 are the masses of the objects in kilograms, r is the distance separating the objects in meters and the value of the proportionality constant G is 6.67 × 10 -11 (N ⋅ m 2 )/kg 2. Spinning planets and their spinning moons orbit around spinning stars, which orbit spinning galaxies.... but neutron stars have such intense gravity, they can rotate this quickly. Over time, the.

Eli5: Why do some planets spin faster than others? - reddit.

However, the time it takes Earth to complete one full rotation on its axis with respect to distant stars is actually 23 hours 56 minutes 4.091 seconds, known as a sidereal day. With this. Answer: Yes. The speed at which a planet orbits the Sun changes depending upon how far it is from the Sun. When a planet is closer to the Sun the Sun's gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun's gravitational pull is weaker, so the planet moves slower in its orbit. -- Jeff Mangum. 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.

Do planets near the sun spin faster or slower than planets... - Answers.

The gravitational pull of the sun is equal to the centripetal force that always acts inward. Gravitational pull or centripetal force due to the sun, F= G×M1×M2/r2. Where G is the gravitational constant and its value is 6.67 × 10-11 Nm2/kg2. M1- the mass of the sun. M2- the mass of any planets.

Why do planets increase in orbital velocity as they get closer to the.

A star forms when a molecular cloud collapses under its own gravity forming a dense core sustained by nuclear fusion. This happens only when the force of gravity pulling in exceeds the outward push of pressure. High-density molecular clouds have stronger forces of gravity pushing in, making it easier to overcome the total pressure within the cloud. The gas giants, the four planets farthest from the Sun, do spin faster than the inner planets. However, rotational speed has almost nothing to do with the distance a planet is from the sun. Having. Is gravity created by spinning something and the faster the spin the more gravity there is or resistance on an object, like a motor? - John hudson (age 48)... could there have been less gravity or more over the life of the planet and has gravity been increasing or decreasing causing other changes.
