Does gravity always pull a spacecraft towards the nearest planet?

Not necessarily. While it is true that gravity is an inverse square relationship with distance, making closeness an important factor, mass is also important, so, for example, if two planets were in the vicinity of a spacecraft, gravity would depend on both mass and distance. Yes, distance is a squared factor, but if one planet were very much larger than the other, it could easily win out, even if it were further away.

Why ecosystems nearest the equator generally experience the highest temperatures throughout the year?
because they are always facing towards the sun.
What keeps the planets from being pulled to the sun's surface by gravity?
The orbital speed of the planets prevent this. The planet's ARE all failing towards the Sun but their horizontal speed means they always miss.
How thick is the earth's gravity field?
Earth's gravitational field extends to infinity. No matter how far you are from the earth, It's gravitational field will always pull you towards it. However, the further you are from the earth, the weaker that force will be.
Why is the gravity pull stronger in the evening?
Its always the same.....
Why do planets are always in orbit?
to keep gravity going
Does gravity always act in the center of earth?
No, the gravity between Jupiter and its moons acts towards the centre of Jupiter.
How would you expect leaves and stems to grow in response to gravity?
Stems will always grow towards light and away from gravity.
Does gravity pull or push objects towards the earth?
The forces of gravity always pull two objects toward each other.
Why do astronauts seen to fly inside their spacecraft?
They are in a state of weightlessness caused be the distance from earth. This is because of one of 2 reasons. If the space craft is in a orbit around the planet, the weightlessness is caused by a constant falling towards the planet, but always misses the ground (you can get the same effect if you are inside an airplane dropping towards earth with more the 9.82m/s). If the spacecraft have left the earth gravity alltogether, there are simply no force pulling the astronauts downwards, making them seem to float. Gravity is caused by the fact that materia bend the time/space field in a way that matter is drawn towards one another. You need a very big mass for this affect to be noticeable though, like for example, the mass of Earth on a person.
How does the moon affect the waters of the earth?
Everything has it's own gravity. The bigger the mass the stronger the gravity. The Earth's gravity pulls the moon towards us, but the moon has its own gravity and, as it isn't strong enough to effect the planet as a whole, so instead it pulls the oceans towards it. As the earth rotates one side is always closest to the moon and is effected the most. This pulling of the oceans towards the moon is how tides work
Why do astronauts feel gravity in space?
There is always gravity between two objects. If the astronaut is in a stable orbit around an object, he/she will not sense any gravity. If he/she is standing on the object, such as the Moon, there will be a sense of gravity. In the case of the moon, its gravity is about one sixth that of Earth. Also, if the spacecraft is accelerating, the the reaction force of the engine will cause the sense of gravity as well.There is also gravity between the astronaut and the spaceship, but that is so small that it will generally not be noticed.
Why ecosystems nearest the equator generally experience the highest temperatures throughout the year?
because they are always facing towards the sun.
Why does acceleration due to gravity always point vertical downward?
Acceleration due to gravity is due to the force of gravitation exerted on a body by the earth. All bodies get attracted towards the centre of the earth. So the acceleration is always pointed vertically downwards.
What is the direction of acceleration due to gravity State with reason?
The acceleration between two bodies is always towards the centre of mass of the bodies in question.
How can you get gravity on moon?
Gravity is there always.
Why do falling objects move faster than objects going upward?
Because gravity always tried to pull objects towards the centre of the earth !
What is a force that pulls objects toward each other?
The force of gravity pulls things towards each other. Magnetism also can pull objects towards each other, but it doesn't always. It can also repel.
