Gravity

Weight is the measure of the gravitational force acting on an object. It depends on the mass of the object and the acceleration due to gravity.

Gravity is typically measured using an instrument called a gravimeter, which detects small changes in gravitational force. These devices can measure the strength of gravity at different locations on Earth's surface. The measurement is usually given in units of acceleration, such as meters per second squared (m/s^2).

Gravity really is one of the four main forces of the Universe.

gravity is an effect and not the cause of anything, no gravitation's, no gravity waves, none of it.

gravity is a dynamic effect. the acceleration of the underlying for of energy focused to the center of a mass.

there is no separate force called gravity, just a dynamic effect we call 'gravity'

By far the easiest method is with the use of a scale. For example, when you

stand on a bathroom scale, it displays the magnitude of both forces of gravity

between you and the Earth.

The value of acceleration due to gravity on Earth is approximately 9.81 m/s^2. This value can vary slightly depending on location, altitude, and other factors.

The more gravity the shorter it will fly. * Gravity has very little to do with aerodynamics. Aerodynamics is the study of the motion of an object through a medium ie. air or water and the disturbances in causes in that medium ie. turbulence etc. The only contribution gravity makes is to the density of that medium.

The force of gravity between the Earth and an object on its surface is what we

call the object's "weight".

What is not generally appreciated is that the object attracts the Earth toward it

with the same force. This means that whatever your weight is on Earth, it's

the same as the Earth's weight on you.

The force of gravity acting on an object is determined by the mass of the object and the acceleration due to gravity (9.81 m/s^2 on Earth). The formula to calculate the force of gravity is F = m * g, where F is the force of gravity, m is the mass of the object, and g is the acceleration due to gravity.

They're not. Gravity is a conservative force and friction is a non-conservative force. This means that the amount of energy expended while in motion opposing these forces varies. When moving in a gravitational field, energy is needed only to move upwards, opposing gravity. No energy is needed to move perpendicular through the field. Think of when a football is thrown through the air. The ball leaves the quarterback's arm and arrives at the receiver traveling almost at the exact same speed (neglecting wind). In contrast, consider moving a heavy book across the top of a table. The longer the path taken to move the book, the more energy is expended.

I guess a small connection may be that without gravity, there would be no force pushing things down, which would remove friction in some cases. But friction is involved in almost every physical system, such as things when rotate.

It is the force of attraction existing between any two objects in the Universe that

possess mass. It is the most important and weakest force. It is the weakest force

because its effect is seen only when there are relatively large masses involved.

e.g

Sun(huge mass)

Earth(large mass)

Force of gravity keeps Earth in orbit around the sun.

Earth (large mass)

we (tiny mass compared to the Earth).

Force of gravity keeps us bound to the Earth.

It is an attractive force that is proportional to the product of the masses of the two objects

and inversely proportional to the square of the distance between their centers.

Specific gravity is the ratio of the density of a substance to the density of a standard reference substance, often water at 4 degrees Celsius. It is a measure of how dense a material is compared to water. Materials with a specific gravity greater than 1 are denser than water, while those with a value less than 1 are less dense.

It's theory that the Higgs Particle "makes" mass in an object. Since any object with mass has an inherent gravitational "tug" by the transitive property the Higgs particle would be said to "make" gravity. If A=B and B=C then A=C

The gravity pressure in a rooftop water gravity tank is determined by the height of the water column above the outlet. This pressure is calculated using the formula P = ρgh, where P is the pressure, ρ is the density of water, g is the acceleration due to gravity, and h is the height of the water column.

Gravity is the force of attraction that exists between all objects with mass. The pull of gravity between two objects depends on their masses and the distance between them, as described by Newton's law of universal gravitation. On Earth, gravity gives weight to objects and is responsible for keeping them grounded.

Gravity exists because of the attraction between two masses. It is a fundamental force in the universe that causes objects with mass to be drawn towards each other. This force is responsible for keeping planets in orbit around stars and holding galaxies together.

I am not sure what you mean by "impact load"; it doesn't seem to be a physical concept. An object that impacts can:* Transfer momentum, calculated as mass x velocity.

* Convert its kinetic energy (1/2 x mass x speed squared) into other forms of energy.

Just use the UGF, which employs 8th-grade math. F = Gm1m2/r2, where G = 6.667 x 10-11 (N.m2/kg2), m1and m2 are the masses of two objects, and r is the distance between them. (Note: you have to convert centimeters to meters.)

The specific gravity of the resultant liquid will be a weighted average of the specific gravities of the original liquids, based on their proportions in the mixture. This means that the specific gravity of the resultant liquid will fall between the specific gravities of the two original liquids.

Please note that the differences are only slight - so slight that you can round

the acceleration due to gravity to a value of 9.8 m/s2, anywhere on Earth,

with reasonable accuracy. The reasons for the (slight) difference are:

1) The Earth is not a perfect sphere. In different places, you are at a different

distance from the Earth's center.

2) The Earth rotates. This produces an apparent centrifugal force. Stated in

other terms, if you are at the equator, while an object falls towards Earth, the

Earth moves away from it due to the rotation (centripetal acceleration).

Gravity exists because mass warps the fabric of space-time, causing objects with mass to attract one another. This warping of space-time creates the force we experience as gravity, which keeps planets in orbit around stars and us grounded on Earth.
