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 greater the mass of the objects the greater the gravity?

The greater the mass of an object, the greater its gravitational pull on other objects. This is described by Newton's law of universal gravitation, which states that the force of gravity between two objects is directly proportional to the product of their masses.

What is the Specific gravity of cocaine?

The specific gravity of cocaine is typically around 1.002-1.005. This value can vary slightly depending on the purity and form of the cocaine.

How is the surface gravity of the terrestrial planets related to the type of atmosphere that they have?

The acceleration of gravity at the surface of each terrestrial planet is proportional

to the mass of each planet and inversely proportional to the square of the planet's

radius, with Newton's gravitational proportionality constant, and is not correlated

in any way with any characteristic of the planet's atmosphere.

In other words: It ain't related.

A brick has a greater mass than a sponge has why is the acceleration due to the gravity the same for both objects?

The acceleration due to gravity does not depend on the mass. For example, if you have two objects, one of which has 10 times the mass of another, it will be attracted with 10 times the force; however, it will also have 10 times the inertia, so the acceleration will be the same.

Force of gravity pulling on a mass?

The force of gravity pulling on a mass depends on the mass of the object and the acceleration due to gravity. The force can be calculated using the formula: force = mass x gravity. On Earth, the acceleration due to gravity is approximately 9.81 m/s^2.

Who shouted saying Eureka after getting into a bath?

Archimedes, the ancient Greek mathematician and inventor, is said to have exclaimed "Eureka!" when he discovered the principle of buoyancy while taking a bath. This event is a famous anecdote illustrating a moment of sudden insight or discovery.

What happens when a person moves from a place with low gravity to a place with high gravity?

When a person moves from a place with low gravity to a place with high gravity, they will feel heavier and may have to exert more effort to perform tasks like walking or lifting objects. Their body may need time to adjust to the increased gravitational force, which could lead to changes in their metabolism, cardiovascular system, and muscle strength.

How does the pressure compare to uranus of earth?

The pressure on Uranus is much greater than on Earth, reaching up to millions of times Earth's atmospheric pressure. This is due to the thick layers of gas in Uranus's atmosphere and its large size, which leads to greater gravitational forces compressing its atmosphere.

Why do things stay upright when there is gravity?

Actually things usually do not stay upright when there is gravity, they usually fall over onto their sides.

For something to stay upright when there is gravity they need to have an active stabilization system using feedback to react to and correct for every time it begins to fall over.

Where does gravity pull everything towards?

Gravity pulls everything towards the center of mass of an object. For example, on Earth, gravity pulls objects towards the center of the planet.

Gravity is least involved in the process of ......?

Gravity is least involved in the process of electromagnetic interactions, which are interactions between charged particles like electrons and protons. These interactions are governed by the electromagnetic force, not gravity.

What does doubling the distance between two objects do to the gravitational force between the objects?

Doubling the distance between two objects decreases the gravitational force between them by a factor of four. This is because gravitational force decreases with the square of the distance according to the inverse square law.

What 2 things affect pull in gravity?

The mass of an object and the distance between objects are the two key factors that affect the pull of gravity. Greater mass between objects results in a stronger gravitational pull, while increasing the distance between objects weakens the gravitational force.

Propane specific gravity?

The specific gravity of propane is 0.495 at 25oC.

The specific gravity of a product can be found on the msds. how do you know if a product will sink in water?

If the specific gravity of a product is greater than 1, it will sink in water. The specific gravity is a measure of the density of a substance relative to the density of water. If the specific gravity is less than 1, the product will float on water.

Why can gravity pull on the suspended particles and grasses in the air?

Gravity is a force that acts between all objects with mass. This includes particles and grasses suspended in the air. The force of gravity attracts these objects towards the center of the Earth, causing them to fall.

Why is weight affected by gravity?

Weight is affected by gravity because weight is the force exerted on an object due to gravity pulling it towards the center of the Earth. The strength of gravity determines the weight of an object; the stronger the gravitational force, the heavier the object will feel.

How can you compare the masses of twop boxes without weighing them?

You can compare the masses of two boxes by directly observing and feeling them, comparing their sizes and densities, and by handling them to get a rough estimate of which one is heavier. Alternatively, you can make use of the known properties or components of the boxes (like material type, dimensions, or contents) to infer their relative weights.

The specific gravity of a product can be found in the MSDS. How do you know if the product will float in water?

If the specific gravity of a product is less than 1, it will float in water. If it is equal to or greater than 1, the product will sink in water. The specific gravity value provides insight into the product's density relative to water.

Is mass or weight the measure of the force of gravity acting on an object?

Weight is the measure of the force of gravity acting on an object. Mass is a measure of the amount of matter in an object. Weight depends on both the mass of the object and the acceleration due to gravity.

What is the centre of gravity of a golf ball?

The center of gravity of a symmetrical golf ball is typically located at its geometric center. This point represents the average position of the ball's mass and affects the ball's balance and stability during flight.

How fast will a 2-kg ball fall from 2 meters high?

It will fall just as fast as an object of any other mass - assuming that air resistance is negligible. That is to say, if an object has a lot of surface area, it will fall slower due to air resistance.

What device is used to test the specific gravity of a cell?

A refractometer is often used to test the specific gravity of a cell.

The specific gravity of a product can be found on the material safety sheet how do you know if a product will flow in water?

You can determine if a product will float or sink in water based on its specific gravity compared to that of water. If a product's specific gravity is less than 1, it will float in water. If it is greater than 1, it will sink. You can find this information on the material safety data sheet (MSDS) for the product.
