Gravity

To calculate the center of gravity for a taper shaft, you would need to consider the varying cross-sectional area along the length of the shaft. You can use an integral approach to determine the centroid of each cross-sectional area and then calculate the weighted average of these centroids to determine the overall center of gravity of the taper shaft. Alternatively, you can simplify the taper shaft as a series of smaller sections with uniform cross-sections and calculate the center of gravity for each section, then determine the overall center of gravity using the weighted average of these section centroids.

Yes, there is gravity in the asteroid belt, but it is much weaker than Earth's gravity due to the belt's low mass and spread-out distribution of asteroids. This weaker gravity allows the asteroids to remain in their orbits without being pulled together into a single body.

Mass and distance are the two factors that play an important role in gravity. The more massive an object is, the stronger its gravitational pull. Additionally, gravity weakens as distance between objects increases.

A gravity measurement of 0.907 refers to the specific gravity of a liquid, indicating its density relative to water. This measurement is commonly used in homebrewing to determine the potential alcohol content of a fermented beverage. A gravity of 0.907 typically suggests that fermentation is nearly complete, with only a small amount of residual sugars remaining in the liquid.

The gravity of Kepler 16b is likely similar to that of Saturn, which is around 1.07 times the gravity of Earth. This means that if you were standing on Kepler 16b, you would feel slightly lighter than on Earth.

The minimum force needed to go against gravity is equal to the force of gravity acting on the object, which is the object's weight. This force can be calculated using the formula F = m*g, where F is the force, m is the mass of the object, and g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth).

The center of gravity of a circular bangle is at the geometrical center of the bangle, which is also the center of the circle. This point is equidistant from all points on the circumference of the bangle, making it the point where the weight of the bangle can be considered to act.

The center of gravity is the point within an object or system where its weight is evenly distributed in all directions. It is the point around which the object will balance itself under the influence of gravity. It is a crucial concept in physics and engineering for understanding stability and balance in various systems.

Gravity increases with the mass of an object. The more massive an object is, the stronger its gravitational pull will be. This is why larger planets like Earth have a stronger gravitational force than smaller objects.

Gravity accelerates the centres of the two masses towards their joint centre of mass. Obviously, if there is a huge difference between the two objects, such as a ball and the earth, the centre of mass of the combined system will be indistinguishably close to the centre of the earth and so it will accelerate the ball towards the centre of the earth. Also, while it will accelerate the earth towards the ball, the force will be too small to measure.

I don't know the reason.

A lot of really clever people have used it, but I think it's more or less useless.

I used to like it, before I really thought about it.

The idea is that the ball distorts the rubber sheet just like mass distorts space.

The distortion of space (spacetime to be exact) is the basis of our modern understanding of gravity.

Some people like this analogy until you point out the problems.

Some things are just really hard to explain.

It was simpler with Isaac Newton. He just had no explanation for gravity.

OK, it's only an analogy, but here's one problem:

The rubber sheet is only 2 dimensional, of course.

Here's another problem : The whole analogy is meant to "explain" gravity.

What causes the ball (mass) to distort the sheet (space)?

The ball is pulled towards the Earth by.........gravity.

Yes, but no , well, I mean........

Answer: Yes. Gravity affects everything. I don't know why this is even a question.

Answer: The reason something is "heavy" in the first place is because of gravity.

Englishman Sir Issac Newton (1643-1727) developed the three laws of motion and the theory of universal gravitation. A more accurate model for the effects of gravity, General Relativity, is sometimes used today. It was developed by the German scientist Albert Einstein in 1915/16. Most people are familiar with Newton's theory which is taught widely in high school physics.

How to calculate the specific gravity of a petroleum product involves using the ratio of the specific product density to that of water. This type of calculation is always determined at 60-degrees Fahrenheit.

The function of gravity is to attract objects with mass towards each other, creating a force that pulls objects towards the center of the Earth. This force is essential in keeping the planets in orbit around the sun and maintaining the structure of the universe. Gravity plays a key role in determining the shape and behavior of celestial bodies, as well as influencing the motion of objects in space.

It is not feasible for an atom to be held together by gravity because gravity is very weak at the atomic scale compared to the electromagnetic forces that bind atoms together. In theory, even if you had an atom small enough for gravity to be the dominant force, quantum effects would destabilize it.

Stronger, as the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. By moving closer together, the distance between the objects decreases, increasing the gravitational force between them.

Air does not affect gravity directly, as gravity is a force of attraction between objects with mass. However, air resistance can have an impact on the motion of objects falling through the air, as it opposes the force of gravity and can slow down the object's descent.

To overcome gravity when leaving Earth, a spacecraft must reach a high enough speed to break free from Earth's gravitational pull. This is achieved by launching the spacecraft at a high velocity using powerful rockets. Once the spacecraft reaches escape velocity, it can overcome Earth's gravity and continue its journey into space.

In my case, the magnitude of the force is 195 pounds. In return, I am

also pulling the Earth up toward me with a force of 195 pounds.

specific gravity is defined as the ratio of the density of the sample/the density of water.

So the specific gravity of water is 1.

Anything more dense than water will have a specific gravity above 1 and will sink.

Anything less dense than water will have a specific gravity below 1 and will float.

The force of gravity on Jupiter is approximately 24.79 m/s^2, which is equivalent to about 24.79 Newtons of force for a 1-kilogram mass.

Yes . If the center of pressure, for the vehicle as a whole, is not located behind the center of gravity (away from the direction of the flight path), then the vehicle will have unstable motion and can tumble. Adding fins to the rear of the vehicle (or increasing fin surface area) will move the center of pressure aft, affording stable flight. A similar effect can be produced by adding weight to the front of the vehicle.
