Gravity

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.

The pull of gravity between two objects depends on more than just the objects. Gravity's effect also depends on the distance between the objects. objects that are closer together have a greater attraction between them. The attraction is weaker when they are farther apart. Gravity exists wherever there is mass, such as in stars and planets.The gravity of each of these objects affects other objects in space.Earth's gravity, for example, reaches millions and millions of kilometers into space.It grows weaker the farther away from Earth you get. Recall that because the moon is less massive than Earth, an astronaut standing on the moon weighs only one-sixth as much as on Earth.The astronaut's weight would change between Earth and the moon.The effect of Earth's gravity becomes less as the distance from Earth increases.

It isn't clear what the distinction is you want to make between "water" and "normal water". Water's density, or specific gravity, can vary slightly, depending on its salt content, other impurities, temperature, and even if it is pure water, its isotopic composition.

The result of the gravitational force is that the object accelerates downward.
When that's combined with its constant horizontal speed, the object follows a
path that curves downward, and is actually a piece of a parabola.

In general, the motion of objects with some horizontal speed under the influence of
gravity is called "projectile" motion, because when the effect of air resistance is
ignored, it describes the motion of things like javelins, cannonballs, and burned-out
rockets. It's a favorite subject commonly found in elementary Algebra and Physics.

Roots of a growing bean seed plant will exhibit positive gravitropism, meaning they will grow downward in response to the force of gravity. This allows the roots to anchor the plant into the soil and seek out nutrients and water necessary for growth.

Yes. Gravity attracts every speck of mass in the universe to every other one,

even though in almost all cases, there's nothing but vacuum between them.

No.

Gravity can be thought of as a force, but that is due to its effect on anything that

possesses mass and/or energy. The effect that gravity exerts on any object is

proportional to the amount of mass that is responsible for the presence of gravity

and is also proportional to the amount of mass possessed by the object experiencing

that gravitational presence.

Therefore a gravitational field will exert a greater 'force' on a greater mass. However,

mass also possesses the characteristic of inertia, which is a measure of resistance to

any change to a state of motion - which effectively is a resistance to the effect of

gravity. Inertia is also proportional to mass.

What this means is that the greater the mass, the greater the pull it experiences due

to gravity but at the same time, the greater is its resistance to that pull.

Hence all falling objects experience the same acceleration due to the effect of

gravity which is not the same as the force. All objects fall at the same rate.

=========================

(Note: Gravity does not exert the same force on all objects, which is the reason

why big people "weigh" more than smaller people do on the same planet.)

The time it takes for a ball to reach the ground depends on the height from which it is dropped and the acceleration due to gravity. Without knowing these specific values, a general calculation cannot be provided.

The forces of gravity are always attractive ... pulling masses together toward

each other.

The math of gravity says that the gravitational force could push objects apart

IF one of them had negative mass. But we haven't ever observed any of that,

and we don't actually know what it is.

When gravity's force is greater than buoyancy, an object will sink in a fluid. This is because the downward force of gravity exceeds the upward force of buoyancy, causing the object to be pulled down towards the center of the Earth.

That only happens when they fall through air. The reason is the friction of the

respective bodies plowing through the amount of air that each is in contact with.

In the absence of air, bricks and cotton would accelerate at the same rate, reach

the same speed at the same time, and hit bottom together.

Without gravity, everything on Earth would float off into space. There would be no atmosphere or oceans, and all living things would have a hard time surviving without the necessary conditions for life. The absence of gravity would also disrupt the orbits of celestial bodies, leading to chaos in the solar system.

The location of an object's center of gravity depends on the object's shape,

and on how its mass is distributed throughout its shape, but not on its size.

The center of gravity of a homogeneous sphere is at the center of the sphere,

no matter whether the sphere's radius is 1 millimeter or 1 light year.

On Earth, it's 9.807 m/s2 . On the moon, it's 1.623 m/s2 .

In othert places, it has different values.

The standard specific gravity of chrome ore typically ranges from 4.2 to 4.8.

Yes, as the ball moves down the incline, gravity pulls it toward the center of the Earth, causing it to accelerate. The force of gravity acting on the ball gives it kinetic energy, resulting in an increase in speed as it moves downhill.

Galileo's experiments showed that all objects fall with the same acceleration regardless of their mass. This discovery led him to understand that objects fall towards Earth due to gravity, a force that attracts objects towards each other. Galileo's observations laid the foundation for the concept of gravitational pull.
