Select TWO answers. O a. Terrestrial planets spin faster, so more gases get flung into space b. Terrestrial planets are colder, so they trap less gas c. Terrestrial planets have weaker gravity, so they can't hold onto thicker atmospheres O d. Jovian planets have more This problem has been solved! See the answer Show transcribed image text. 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.
Ask Astro Can planets be pear-shaped, or are they all spheres?.
The actual force of gravity exerted by the planet wouldn’t change. However, some of the effects of rotation change our experience of gravity. The centrifugal force of the rotation counteracts some of the force exerted by gravity - so we feel like we weigh a. 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.”.
Gravity: A simple introduction - Explain that Stuff.
The presence of life might influence how fast a planet spins, releasing gases such as oxygen that can crank up how quickly a world turns, a new study finds. Earth currently takes about 24 hours to.
Physics - How would fast rotation affect gravity.
He also assumes that the planet starts out rotating at the break-up velocity (about 8 hours ). Without any slow-down, Jupiter simply speeds up as the planet contracts in order to conserve angular momentum. But with magnetic braking, Jupiter first spins down to a rotation period of 36 hours in about 25,000 years. Why Do Planets Spin? Round and round the planets spin. This is simply the result of the initial rotation of the cloud of gas and dust that condensed to form the Sun and planets.As gravity condensed this cloud conservation of angular momentum increased the rotational speed and flattened the cloud out into a disk.
Planets in Order From the Sun | Pictures, Facts, and Planet Info.
Black holes formed after the Big Bang as stars evolved and died. And because the stars that created the black holes were originally spinning, so were their progeny. Indeed, even though stars.
Can planets with way more gravity than Earth reduce their.
You might object that these are moons around a planet, not planets around a star, but gravity is gravity, mass is mass, and orbits are orbits. The exact magnitude is the only difference, while the.
Does the moon rotate? | Space.
As it condensed out of the disk, each planet began to spin faster; the more mass the planet had, the more angular momentum it had, and hence the faster it would spin. (This takes place even though the Jovian planets are physically bigger than the terrestrial planets - the key is that they have relatively more mass than radius.).
Mercury’s Spin and Gravity Reveals the Planet’s Inner Core.
As empty as space is, it does have some forces - some particles there and there, radiation from the stars, gravity of some planets. It could not spin forever, but it would come close to it, actually. Meanwhile a fidget spinner would spin much shorter, because of its internal friction in the bearing. 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.
Artificial gravity - Wikipedia.
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. 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. What do the inner planets have in common? They are all small, dense, and rocky.... The four outer planets are much larger and more massive than Earth and they do not have ____. solid surfaces.... This gravity keeps gases from escaping forming _____. Thick atmospheres.
Discovery Alert: A Closer Look at Mercury's Spin and Gravity.
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.
Q & A: Why do Planets have Gravity - Department of Physics.
Our planets have continued spinning because of inertia. In the vacuum of space, spinning objects maintain their momentum and direction — their spin — because no external forces have been applied to stop them. And so, the world — and the rest of the planets in our solar system — keeps spinning. physics. solar system.
Why Do the Planets of Our Solar System Revolve Around the Sun?.
It takes less time because the length of the orbit is shorter (a smaller orbit), but it also moves faster in its orbit. Thanks to gravity, it has to move faster in its orbit to stay in orbit! Below are the distances of the terrestrial planets from the Sun and the length of their years.
Yes, Two Planets Can Both Share The Same Orbit - Forbes.
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. This is because it takes more time for the larger planet to complete one full rotation. Kepler's laws tell us that the closer a body is to the object it orbits, the faster it has to move to stay in orbit. This means that the material on the star-ward side of the protoplanet is moving faster than the protoplanet itself. As it falls towards the centre of the protoplanet, it pulls further from the star, causing its speed to slow down.
