Gravity

The same way you "beat the pull of gravity" to move yourself from the first floor

up to the second floor. You exert an upward force on your body greater than the

force that attracts the earth and your body toward each other, and the result is

that they separate. This can be accomplished using an escalator, elevator, winch-

line, staircase and leg muscles, etc.

Theists have always held that God was responsible for the creation of the universe. Stephen Hawkin now says that gravity was responsible for the "Big Bang" and therefore the creation of the universe. One way of looking at this is that God is gravity. Of course, theists would not accept this simplistic conclusion.

The center of gravity is the point where the weight of an object is concentrated. When the center of gravity is properly aligned over the base of support, it helps to maintain balance. If the center of gravity is outside the base of support, it can cause the object to tip over.

Gravity was the first force to split from the other three fundamental universal forces (these being the electromagnetic, strong nuclear and weak nuclear forces) during the early expansion of the universe - around the end of the Planck epoch - through phase transitions of symmetry breaking. This basically defined the gravitational relationship among the others as we know it today, and hence gravity as a unique force has existed for the entirety of the known universe.

However, beyond that, gravity is at best hazy and at worst unexplainable because of those same definitions and properties. Active research includes gravity and how it works as a major focus, with efforts so far unable to unify it with the other three forces.

Gravity affects anything with a weight. Take a feather for example; it may fall slowly if you drop it, but the speed has nothing to do with gravity. It is infact air resistance that slows the feathers descent. weightless things like gases have no gravitational pull, so they are able to move about freely in the air. I hope that wasn't too confusing :S

There is nothing special about the center of the Earth itself; the attraction is in that direction, due to the accumulated effect of the attraction from different parts of the Earth.

At the center of the Earth itself, the gravitational attraction towards the left, for example, by some pieces of planet Earth, would be exactly compensated by gravitational attraction towards the right, by other pieces of the planet.

Gravity holds the Earth and its atmosphere together, allowing the sky to remain in place around our planet. This force also influences the movement of clouds and the behavior of celestial bodies, such as the sun, moon, and stars, in Earth's sky.

Gravity is strongest at the center of the Earth because the mass of the entire planet is concentrated in that location. This concentration of mass creates a gravitational force that pulls objects towards the center. This is why objects, including ourselves, feel a force pulling us towards the Earth's core.

Gravity affects your brain by constantly pulling it downward, causing the brain to be anchored in place within the skull. Over time, this can lead to compression and deformation of brain tissue, as well as increased pressure within the skull. Additionally, gravity influences blood flow in the brain, with more blood pooling in the lower regions when standing upright, potentially impacting cognitive function and overall brain health.

The mass of an object remains constant regardless of the force acting on it, including Earth's gravitational pull. Weight, on the other hand, is a measure of the force exerted on an object by gravity, which can vary depending on the strength of the gravitational field (like on different planets).

No, the increased gravity would make it harder for people to float on water. The extra force pulling them down would make it more difficult for them to displace enough water to stay afloat without some external support.

Any time a person falls, they experience reduced gravity for a short time.

If they fall a greater distance, the more likely they will experience something close to zero G.

Sky diving, riding a roller coaster/ amusement park ride with a free fall component can get close to zero g. If you've been in a plane that hit turbulence and dropped quite a ways, you may have experienced zero gravity.

Point is, zero is experienced during free fall, which is exactly what the astronauts are doing when they are in orbit.

Yes, all galaxies in the universe are bound by the force of gravity, which governs their interactions with one another as well as their internal structure and motion. Gravity is the dominant force shaping the formation and evolution of galaxies over cosmic timescales.

Most rockets are intended to get out of Earth's atmosphere, but many do come back down eventually.

Those that don't either have enough velocity and acceleration to get beyond enough Earth gravity to leave its orbit; others are set to exactly arrive at a particular orbit and stay there. This occurs because they are moving away from Eartha t the same rate they fall towards it.

Yes, people on the space station in a geosynchronous orbit above Earth would still experience microgravity, which can make them feel weightless. This is because they are continuously falling towards Earth due to the balance between their forward motion and the planet's gravitational pull.

Only partially. Meteoroids passing near Earth are affected by Earth's gravity, but they are traveling far faster than escape velocity, that gravity is usually insufficient to cause an impact. Rather, meteoroids strike Earth and its atmosphere when their trajectories around the sun intersect that of Earth such that they will pass through the same place at the same time. In the case of a near-miss, Earth's gravity will alter an asteroid's or meteoroid's orbit. In some cases this change can lead to a collision later on.

The effects would only combine for an object outside the Earth-Moon system (such as an asteroid). Otherwise, objects near the Earth and Moon will experience gravitational effects from both. The Earth's gravity holds the Moon in its orbit, and the Moon's gravity affects the Earth, notably causing the ocean tides.

Gravity on Earth is a fundamental force of nature that arises from the mass of the planet. As all objects with mass exert a gravitational force on each other, the Earth's mass pulls objects towards its center, creating the force of gravity that holds everything on its surface.

I guess mother nature did. The first mathematical description of gravity came from Sir Isaac Newton, so the modern study of the effects of gravity were initiated by him.

Gravity is the force by which a planet or other body draws objects toward its center. The strength of gravity depends on the mass of the objects and the distance between them. It is responsible for keeping celestial bodies like planets and stars in orbit.

Yes, particles in a nebula are attracted to one another due to gravity. As the particles come together under the influence of gravity, they can clump together and eventually form stars and planets. This gravitational attraction is an essential process in the formation of celestial objects in space.

The center of gravity for a triangular region is at the point where the three medians of the triangle intersect. The medians are the line segments that connect each vertex of the triangle to the midpoint of the opposite side. This point is also known as the centroid of the triangle.

Much weaker. Pluto is a dwarf planet and much less massive than earth, so it has lesser granitational force at it's surface.
