Gravity

-- First of all, I always had the impression that mountains are on land,

at least those that you can stand on. Be that as it may, however . . .

-- Technically, you would weigh slightly less on a mountaintop than you do

when you're on the flats, because on the mountain, you're farther from the

Earth's effective center of mass.

But you'd need some pretty good equipment to measure it. I worked it out once

for a person on an airliner cruising at 35,000 feet ... roughly a mile higher than

the highest mountaintop on Earth.

Compared to his weight at sea level, he weighs about 0.33 percent less when he's

up at 35,000 feet. For a 200-pound man, that's a difference of about 10.6 ounces.

You can use 10 when you only need a rough answer. Use 9.8 when you want your

answer to be more accurate, and if you want it still more accurate, then look up a

more accurate number for the acceleraiton of gravity. (9.8 is a rounded figure.)

Gravity never truly ends; it just becomes weaker as you move further from massive objects like planets and stars. In space, the effects of gravity are felt at vast distances, even between galaxies. The exact point at which gravity becomes negligible is not clearly defined.

Weaker. Mercury is a teeny tiny planet.

Gravity has kept me in my chair today. This has made it immeasurably easier to

do my work.

Gravity has also been instrumental in keeping a plentiful supply of atmosphere

conveniently located in my proximity. I in turn have persisted in breathing,

rhythmically and steadily as far as I know, all of which has undoubtedly had

a salutary influence on my overall performance.

The acceleration due to gravity on or near the Earth's surface is about

9.81 meters per second2 .

The forces of gravity between the Earth and a mass on or near the surface

are 9.81 newtons per kilogram in each direction.

Gravity is a force of attraction between two objects with mass. The larger the mass of an object, the stronger its gravitational pull. Gravity affects objects by pulling them towards each other, causing them to accelerate towards each other. It is responsible for keeping planets in orbit around stars and for the weight we feel on Earth's surface.

Any time you want. You only have to provide a force vector with magnitude
greater than the magnitude of the gravitational force, acting in the direction
opposite to the direction of the gravitational force.

Sound complicated, science-fictional, and probably impossible ?

That's exactly what you do with your leg muscles when you want to move
your body up some stairs.

The total momentum of marbles after a collision is equal to the sum of the momentum of each individual marble. Momentum is a vector quantity, so both the direction and magnitude of each marble's momentum must be considered when calculating the total momentum of the system.

Firstly, gravity is a force.

The strongest gravital effect would be right at the centre of the earth - the centre of its mass.

The greater one's altitude, therefore, the lesser the effect and pull of gravity - being further from the earth's centre.

Tell them it is a pull that the earth and other things in space have that make things fall towards them.

Because it depends on things that can change.

The force of gravity between two masses is proportional to the product of the
masses and inversely proportional to the square of the distance between their
centers. If either of their masses changes, or the distance between their centers
changes, then the gravitational force between them changes. If not, then the
force is constant.

Gravity is typically measured using a tool known as a gravimeter or accelerometer. These devices detect the gravitational pull exerted by an object, such as the Earth, and can provide measurements of gravitational force.

The force with which gravity pulls an object is called its weight. This weight is determined by the mass of the object and the acceleration due to gravity at that location.

Gravity is the force that attracts two objects with mass towards each other. It is responsible for keeping planets in orbit around the sun and objects on Earth's surface. Gravity is described by Isaac Newton's law of universal gravitation and Albert Einstein's theory of general relativity.

Mabel has sleepovers with Candy and Grenda and Dipper's not happy about sharing the room with Mabel. Soos finds a secret room and then the twins compete over who should have it. The twins switch bodies after Dipper rubs his feet on the carpet and touches Mabel's hand. Later, everyone switches bodies. In the end Mabel and Dipper stays in different rooms, but they're sad about this. Dipper comes to Mabel and then they share the room again. They play mini golf and Dipper hits Stan.

You cannot increase gravity, but you can increase the force of gravity on a piece of matter with mass by

1. Making the piece of matter larger
2. Making it more dense
3. Moving it closer to the center of a separate piece of matter.

Yes, gravity exists between two objects that have mass.

The force of gravity between two objects is stronger when the product of their
masses is big than it is when the product of their masses is small. It doesn't matter
whether one object is humongous and the other is tiny, or whether the mass is
split equally between them. What matters is the product of the masses and the
distance between them.

The center of gravity of a rhombus is located at the point of intersection of its diagonals. This point is equidistant from all four corners of the rhombus. It is also the centroid of the figure, which means that if you were to balance the rhombus on a point, that point would be the center of gravity.

True. The center of gravity is the point where all the body's mass is concentrated. It does not contribute directly to individual stability, but rather influences how the body must position itself to maintain balance. Other factors, such as the base of support and the line of gravity, play a more direct role in stability.

Because they're both falling through air, and the leaf has to slip and slide through
the air.

If you drop a leaf and an apple in a tube with no air inside ... and also add a bowling ball,
a parachute, a rock, and a feather if you want to ... they all fall at the same rate, and
hit the bottom at the same time.
