What else can I help you with?
Gravity on the moon is less than on the earth True or False?
True. Gravity on the moon is about one-sixth that of Earth's gravity.
Which is not true in the inner planets?
The inner planets are closer to the Sun compared to the outer planets, have solid rocky surfaces, and are smaller in size compared to the outer planets.
Is it true that- gravity holds planets in orbit because planets are attracted to each other's gravitational force?
No, gravity holds planets in orbit around the sun because the sun's gravity pulls on them. This gravitational force between the sun and planets keeps them in their respective orbits. The force between planets themselves is much smaller and mainly affects their interactions with each other rather than their orbits around the sun.
Which scientist discovered that planets move faster when they are closer to the sun?
That's one of Kepler's three laws of planetary motion, which he figured out fromstudying Tycho's lifetime of watching the planets and keeping notes.About 100 years after Kepler, Newton wrote his theory of universal gravitation,and showed that if gravity is true, then the planets mustbehave that way.
What causes the planets that are closer to the sun to move faster?
Basically it is because the force of gravity is greater nearer the star so it acclerates the star even more. A more mathematical answer: The force of gravity is given by the formula F = GMm / r^2 Where G is a really small number used as a constant of proportionality, M is the mass of the star, m is the mass of the planet and r is the distance between them. The force of gravity is acting as a centripetal force on the planet and we know that for a centripetal force is F = mv^2 / r Where v is the velocity (speed) of the planet. We can combine the two formulas to give v = sqrt(GM / r) So a planet will move faster if the star is more massive or it distance from the star is smaller.
Is it true that the bigger the planet the more gravity it has?
Well sometimes it is and sometimes it isn't. That old saying is not nessary true. Because there are plenty of planets in the universe that are the same size as earth but have less gravity than earth.
Are the outer planets much closer together than the inner planets?
No. The reverse is true.
Gravity on the moon is less than on the earth True or False?
True. Gravity on the moon is about one-sixth that of Earth's gravity.
Is it true that Earth is the only planet with gravity?
No, that's not true. All planets, moons, and stars have gravity. Actually all objects have gravity, it's just not very strong for small objects.
Which is not true in the inner planets?
The inner planets are closer to the Sun compared to the outer planets, have solid rocky surfaces, and are smaller in size compared to the outer planets.
Is it true that- gravity holds planets in orbit because planets are attracted to each other's gravitational force?
No, gravity holds planets in orbit around the sun because the sun's gravity pulls on them. This gravitational force between the sun and planets keeps them in their respective orbits. The force between planets themselves is much smaller and mainly affects their interactions with each other rather than their orbits around the sun.
Is it true gravity wind and water on planets surface cause weathering and erosion?
YES!
Why is gravity in some planets more some not?
Gravity is stronger on some planets because the planet's core is much more dense. Making it's gravitational pull stronger. Which is making gravity stronger. that is sortof true
Is it true that the force exerted by gravity is stronger if two objects are closer?
Yes it is because because hte closer they are the greater the force.
Newton applied his laws of motion to the problem of the motions of the planets. he assumed that it was gravity that held them into their orbits. true or false?
true
Is this question true or false when there is less gravity there is less gas?
False. The presence of gravity does not directly affect the amount of gas in an atmosphere. Factors such as temperature, pressure, and chemical reactions play a larger role in determining the composition and amount of gas in a given atmosphere.
A meteor is an asteroid that has been captured by a planets or a moons gravity and had been pulled away from the suns gravity true or false?
false, meters are asteroids in the earth atmosphere
