Gravity

One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

What Is The Specific Gravity Of mixture of Gas And Water?

The specific gravity of a mixture of gas and water would depend on the proportions of gas and water in the mixture. Gas would typically have a much lower specific gravity than water. The specific gravity of the mixture can be calculated by taking into account the specific gravity of each component and their respective proportions in the mixture.

What is the value of gravity in fps system?

The value of gravity in fps system is 5.3 ft/s2.

Does more weight means more gravity energy?

Weight is a measure of the gravitational force acting on an object due to the mass of that object. More weight does not equate to more gravitational energy, as the energy associated with gravity depends on the mass of the object and its distance from another massive object, such as the Earth.

Acceleration due to gravity is usually equal to m s?

Acceleration is measured in m/s2, not in m/s. Close to the Earth's surface, the

acceleration due to gravity is approximately 9.8 m/s2. It varies a bit, depending

on the exact location, but not enough to be noticeable except by careful measurement.

Why does water in a siphon flows upward against gravity?

Water in a siphon flows upward against gravity due to atmospheric pressure pushing the liquid up the shorter arm of the siphon tube. The weight of the water in the longer arm creates a pressure difference that drives the flow to overcome gravity and flow up the tube.

How does gravity the hold the sun there?

There is an intense amount of gravitational energy at the centre of the solar system, this is what is holding the sun together and keeping the reactions between the hydrogen atom happening That same energy holds the planets in orbit, so its pretty strong =]

How is the centre of gravity used?

The center of gravity is used to determine the balance and stability of an object or system. It helps in predicting how it will behave when subjected to outside forces, like gravity or external loads. By understanding the center of gravity, engineers and designers can optimize the design and placement of components to ensure safe and efficient operation.

Where do you use the silver key in the gravity falls game pines quest?

You can use the silver key in the Gravity Falls game "PinesQuest" in the Mystery Shack to unlock the attic door. The attic contains valuable items and clues to help you progress further in the game.

What does it mean to displace gravity?

To "displace" something means to push it away. Presumably somebody was thinking about pushing the force of gravity away from a certain area, thus canceling gravity. It doesn't seem likely that this is possible at all.

Does the force of gravity change an object's mass?

No, the mass of the object is the same, no matter what gravitational forces (if any) are affecting it. The weight changes, though, because weight is defined as the force of gravity on an object. Thus, if you are in zero gravity, you have zero weight but not zero mass.

What is the force of gravity of mercury in newtons?

The force of gravity on Mercury is about 3.7 meters per second squared, or 3.7 N/kg. The force of gravity on an object on Mercury will depend on the object's mass.

When was Super Extra Gravity created?

Super Extra Gravity was created on 2005-10-14.

Do equal volumes of different substances have equal weights?

No, it depends on the specific gravity (or relative density) of the substance. E. g. Compare the weighs of 1 cubic metres of cork and iron.

Does gravity pull all objects together?

yes or no dumies it is in your book read it and you have a big butt

How much gravity in Ceres?

The gravity of Ceres is 0.27 m/s² or 0.028 g

What is the effect of gravity on weight?

Gravity is what gives an object weight. The force of gravity pulls objects towards the center of the Earth, giving them a weight relative to their mass. Weight is a measure of the force of gravity acting on an object's mass.

Do rocks have gravity?

No, rocks do not have gravity. Gravity is a fundamental force that exists between all objects with mass, including rocks. Rocks are subject to the force of gravity, just like any other object on Earth.

Does gravity stop a ball from rolling?

Momentum is the product of mass and velocity. When an object slows down, the object reduces in velocity. Since Mass is constant, when velocity reduces momentum reduces. thus momentum can be what stops a rolling object.

However, a resistive force the reason for the reduction of velocity and subsequently halting.

What is a gravity and proximity sensor?

A gravity sensor is a type of sensor used in smartphones and other devices to detect changes in orientation or tilt. It helps adjust the screen orientation according to the device's position.

A proximity sensor is used to detect when a nearby object is within a certain range of the device. It is often used in smartphones to disable the touch screen when the device is close to the user's face during a call to prevent accidental touch input.

Is it true that as objects accelerate toward each other the gravitational attraction between them decreases?

No, the gravitational attraction between two objects increases as they accelerate toward each other. This is because gravitational force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them, so as they get closer, the force of attraction becomes stronger.

What is the gravity of loading a can?

Gravity is the force that pulls objects towards each other, given by the equation F = G(m1 * m2) / r^2. When loading a can, its weight and the force of gravity will be acting upon it, causing it to be pulled downwards towards the Earth's center.

What does 1.015 specific gravity in urine mean?

It means that any volume of that urine weighs 1.015 times as much as the same

volume of pure water weighs. A properly trained physician or medical laboratory

technician can often identify and evaluate several normal or abnormal conditions

based on the measured specific gravity of an individual's urine.

What effect does the acceleration due to gravity on the moon have on a simple pendulum?

The lower acceleration due to gravity on the moon causes a simple pendulum to swing more slowly compared to Earth. The period of the pendulum is longer on the moon because gravity plays a role in determining the speed at which the pendulum swings back and forth.

Why acceleration due to gravity does not changes when earth stops rotating?

Well first of all, you don't know that to be true, because the Earth has never

stopped rotating to let us observe what happens.

But we do know that the statement is true. The deceptively simple formula for

calculating the gravitational force between two masses tells us that the force

depends on the masses and the distance between them. The fact that they

may be rotating, tumbling, flopping around, orbiting in a giant ellipse, or sailing

through the blue doesn't appear in the formula, because none of that makes any

difference in the forces of gravity.

How long was gravity on earth?

Gravity has been present on Earth since the formation of the planet around 4.5 billion years ago. It is a fundamental force that has influenced the structure and evolution of Earth, shaping everything from the atmosphere to the movement of tectonic plates.
