Gravity

Just because gravity happens go to a physics class i go to harvord right now and never got below 99 percent on scores

-- The forces of gravity between two objects act along the line between their centers.

-- For objects on Earth, one of the objects involved in mutual gravitational forces

is always the Earth, just because it's the biggest mass around.

-- So any object dropped on or near the Earth experiences a gravitational force that

attracts it toward the center of the Earth.

-- The direction from New Zealand toward the center of the Earth is not the same as the

direction from Scotland toward the center of the Earth. In fact, they're nearly opposite.

When the total amount of mass in a galaxy is computed, and the total amount of gravity is calculated there is a discrepancy. There appears to be more matter in the galaxy than what can be observed. Dark matter was theorized as being matter that exists but does not interact with electromagnetic radiation. Because of this, it cannot be seen. That is why it is called dark matter.

The moon's gravitational force does influence Earth's tides and rotation, but it is not expected to drastically alter Earth in the future. The moon's orbit is stable and changes occur slowly over millions of years rather than in a drastic manner.

At a greater depth, there is a greater pressure, period. The amount of water in the dam is irrelevant.

Ocean tides are the result of the gravitational attraction forces
between the sun, moon, and ocean water.

Gravity is the major force in the Universe controlling matter. Gravity controls the structure of the Universe.

In a closed universe, the expansion will eventually halt and contraction due to the pull of gravity. Check out the 'Electric Universe Model'. It should provide more detailed explanations. Beware! It's a deep subject and one can get lost/confused. Take it slow to groc in fullness. (BTW The Closed Universe Model mostly proven false or highly unlikely.) It is understandable that you are having trouble understanding the closed universe theory since as has already been previously mentioned it is most likely not true. What I think most people struggle to grasp is why the universe can at present be expanding but then this sudden change occur where this expansion is not only halted but reversed. This kind of question rivals questions like why did the Big Bang happen. The truth is we don't really know why this might happen, but it was established as a possible answer since if it were true, we could then explain the Big Bang. It was a solution designed to dodge a question.

gravity feed lubrication is when the lubricant is pumped to the top of the object needing lubrication, and falls on top of the object, covering it and lubricating it. An example would be a wet sump car engine.

weight is the effect caused by gravity. if gravity increases, so does your weight!

Isaac Newton is credited with discovering the concept of gravity. He formulated the law of universal gravitation, which explains how objects with mass attract each other.

Yes. Gymnasts learn gravity way before they learn it in school!! We have to learn that when doing a flip you have to set (shoot up in a strait body really fast) before flipping so the gravity doesn't pull you down before the flip is done!

Gravity is essential for keeping us rooted to the ground and maintaining the structure of our planet. It plays a crucial role in shaping the universe and governing the movements of celestial bodies. Without gravity, life as we know it would not be possible.

No one invented the gravitational pull of the earth. Gravity has always been here and will remain. The earth's gravity is a function of the mass of the earth. We know that anything with mass has gravity associated with it. Those of us who live here have a small amount of mass, and the earth attracts us to its surface because of gravity.

The density of air changes with change of temperature, therefore changing it's mass. In other words, the molecules that make up the composition of air move farther apart with a rise in temp and, of course, just the opposite with a decrease in temp. Since temperature changes the mass of air, gravitational pull from the earth will change proportionately.

when it is in motion

some people say he was in the garden having tea!!

Gravity is a force on earth that pull everything down. On the moon there is less gravity than on the earth

Two main types of gravity erosion are mass wasting, which involves the downslope movement of rock and soil under the influence of gravity, and erosion by gravity-driven processes like landslides, rock falls, and slumps. These processes are influenced by factors such as slope gradient, rock and soil properties, and the presence of water which can increase the likelihood of erosion.

Gravity affects the string by applying a force (dm).(g) on every particle of mass dm. Thereby, it produces a damping effect on the string.

The force of gravity opposes acceleration away from the source of the gravity. This is expressed as "centrifugal force" or the perpendicular component of a tangential velocity. The balance between these keeps the planets in orbit around the Sun.

Yes. Every object in the universe has gravity.

However, the force of gravity decreases proportionally to the SQUARE of the distance, so even though Sirius is quite large and very massive, it is also very far away - so we don't feel a bit of it.

This is why we feel the gravity of the Earth, which isn't nearly as massive as our Sun, but is right here - not 93,000,000 miles away.

Mass wasting

Yes, yes you can. But the only thing is, you have to be travelling at a rate of 17,500 miles per hour to get out of the earth's gravitational pull. This speed cannot be reached without rocket or jet assisted take-off. Or light speed but we can't control that yet. :}
