Q & A: Why do Planets have Gravity - Department of Physics.

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. Planets originate as dust particles that are attracted to each other mainly by static electricity. Once all those accumulated particles build up enough mass, then gravity will attract other masses.

Why do planets closer to the sun orbit faster than the.

Every day, the Earth spins once around its axis, making sunrises and sunsets a daily feature of life on the planet. It has done so since it formed 4.6 billion years ago, and it will continue to do. This minute amount of rotation started off by a huge scale increases and collapses under gravity. There' conservation of angular momentum so it speeds up and speeds up. Some galaxies will be spinning in one direction, others in another direction. Chris - We should see a roughly equal proportion of each. Dave - Basically random.

Why do bigger planets have shorter days? - Science Forums.

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.

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

The speed of a planet’s rotation depends on a few different factors. One is the distance from the sun. The closer a planet is to the sun, the faster it will rotate. This is because the sun’s gravity is stronger on planets that are closer to it. Another factor is the size of the planet. The larger the planet, the slower it will rotate. Answer (1 of 4): Not necessarily. A planet with more mass will have more inertia (the tendency to keep moving in its current path), but may or may not be travelling faster than another planet that's lighter. How fast a planet travels purely depends on the gravity that it experiences from other c. 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.

Does the inner planets have more or less gravity... - Answers.

>> Also why do rock planets spin so much slower? TreBert >Rocky planets are somewhat hollow or of low core density, and gassy >ones have a heart of gold or rather one of thorium, uranium and many. So, it applies to all objects as they all spin on an axis. It is an angle measured in degrees relative to the plane of its orbit around the Sun (for a planet or asteroid) or a planet for a moon. Some values: Mercury: 0.01 degrees Venus: -177.4 degrees, Earth: 23.44 degrees, Moon: 6.688 degrees, Mars: 25.19 degrees. 4. The answer to why planets have moons is relatively simple. The planets have moons (or don't) due to how they formed, their location, and gravitational pull. As our technology and the instruments continue to improve, there are endless possibilities. With each passing year, more moons are discovered. More moons and information about them will.

Why do planets rotate? (Intermediate) - Curious About Astronomy? Ask an.

Answer (1 of 4): "Can planets with way more gravity than Earth reduce their gravity by spinning really fast?" The Earth itself is an example of why the answer is "Yes." If you use "weight" scales (e.g., the spring-loaded type), you'll find that you weigh roughly 5% less near the equator than you.

How would gravity change on a planet rotating around itself very.

Along the equator of a planet, a circle half way between the north and south poles, gravity is holding the edges in but, as it spins, stuff wants to spin out like mud flying off a tire. Saturn and Jupiter are really big and spinning really fast but gravity still manages to hold them together. That's why they bulge in the middle. 2 Answers. The same reason (almost) all of them rotate in the same direction: because of the conservation of angular momentum. Before a star and its planets exist, there's just a cloud of disorganized gas and small molecules. The Solar System formed from such a cloud around 4.6 billion years ago. On that scale, there is some small amount of. Gravity and spin. Is it because the Earth spins that we have gravity? - Anonymous. sydney,.

Do all planets have an axis? - Answers.

As the cloud collapses, the averagedirection of motion of the cloud is kept — and as gravity pullseverything closer to the center, the conservation of angular momentumcauses that average motion to speed up. You can do this experiment athome if you have a chair that spins.

Can a planet be bigger than Earth but still have a habitable gravity.

Option 1: A Paragraph. We can write a paragraph about how long days last on other planets. On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast.

Gravity does not always make spheres - The Flat Earth Society.

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. 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.

Q & A: Do all planets have gravity? | Department of Physics.

Unlike the spherical shapes of terrestrial planets, the jovian planets are all slightly oblong. The jovian planets rotate much faster than any of the terrestrial worlds. Gravity by itself would make a planet spherical, but their rapid rotation flattens out their spherical shapes by flinging material near the equator outward. Obviously this is much more than the downward accelleration due to gravity, so this system wouldn't be stable and the ridiculous factor of 10,000x higher spin speed makes no sense. What if the earth was only spinning 10x faster? Then ω would be 727 x 10-6 rad/s, and the centrifugal accelleration at the equator 3.4 m/s 2. That's a significant fraction of the. How do planets orbiting the Sun and skaters doing a spin both conserve angular momentum? Wiki User. ∙ 2018-03-07 05:28:20. Add an answer.

Staying grounded in space requires artificial gravity.

Along the equator of a planet, a circle half way between the north and south poles, gravity is holding the edges in but, as it spins, stuff wants to spin out like mud flying off a tire. Saturn and Jupiter are really big and spinning really fast but gravity still manages to hold them together. That's why they bulge in the middle. The planets of the solar system revolve around the Sun due to the force of its gravitational pull. The elliptical orbit of the planets is a result of the Sun's gravity, which acts to pull the planets closer, balanced by the forward momentum of the planets. The solar system was formed billions of years ago from a large cloud of gas and dust. Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light.

What Causes Gravity on Earth? - Sciencing.

Because of this, Mars has 0.38 times the gravity of Earth, which works out to 3.711 m/s 2. Gravity on Jupiter: Jupiter is the largest and most massive planet in the solar system. Its mean radius,. 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. However, the effect of spinning is most on equator and least at. Things would get more catastrophic the faster we spin. Losing gravity and weight Centrifugal force from the Earth’s spin is constantly trying to fling you off the planet, sort of like a kid on.

The surface gravity on Venus is slightly larger than that on Uranus. Mars is similar to Earth in many ways, but it is a lot smaller in size and mass. Mars is only 0.1 times the mass of Earth, and its surface gravity is not much larger than Mercury’s. Mars is a fairly dense planet, and so its surface gravity is probably larger than you would. No. Jupiter has. Defined as the gravitational accelleration g at the surface, or, for the gas Giants, at the “edge”, we compare Earth's g (9.81 m/s2) with Jupiter's (about 25); Neptune is 2nd (~11), 3rd is Saturn (10.4). Remarkably enough, Uranus’ g is slightly less than Earth's with 8.7.
