Gravity

Yes, air resistance affects a ball being thrown by creating a force that opposes its motion through the air. This force acts to slow down the ball and alter its trajectory, especially at higher speeds or in the presence of turbulent air flow.

If gravity wasn't here we would be thrown off the planet. Also the nanosecond you lifted up your foot even a millimeter you would keep going forever until you hit something. You cant run without gravity.

As the mass of a body or things is constant , the weight only depends on the the gravity 'g'. As the gravity increases with the decrease of the hight of the mass from the centre of the earth , the mass also increases with the decrease of hight from the centre of the earth.

A hydrometer is commonly used to measure the specific gravity of a liquid. It is a glass or plastic tube with a weighted bottom that floats in the liquid, and the specific gravity is read at the level of the liquid where the hydrometer surface intersects.

First off it is important to realize that weight is not the same as mass. (Some people make that mistake, so I thought it best to clear that one immediately). The mass of an object is unaffected by free fall.

Now for the question, weight is the force that stops you from free fall. In this regard it is automatically zero in free fall since there is no force opposing you. However, it is instructive to consider this somewhat further.

How do you measure weight? Well, here on Earth you might simply stand on a weight meter and read off what it says (even though it usually gives its answer in kilograms, you can convert these into Newtons using the gravitational constant). How does this device measure your weight? Usually it contains a spring of some sort that provides a force stopping you from crushing it. This force is what is measured, and this force is what stops you from falling through the meter. It is sometimes referred to as the normal force. This is your weight.

Now imagine doing the same in free fall. Say you jump out of spaceship above Earth (to neglect air resistance), in a spacesuit (to neglect you dying from lack of said air), and a weight meter. How would you proceed to use it?

You can put it under your feet, but the meter is accelerated towards Earth in the same manner as you (barring any tidal effects), so the spring is not needed to stop you from crushing it. As a result the meter shows you are weightless. You move towards the meter due to gravity, but the meter moves away just as quickly due to the same gravity. The overall point then is that you are weightless because your acceleration towards Earth exactly cancels the gravitational acceleration in a way.

This is because an object's resistance to acceleration is its mass, and the strength of the gravitational force is also depending on its mass and these quantities drop out of the equation and everything falls with the same speed.

Saturn because Earth has less miles of Saturn because the greater the planet, the more gravity it contains. Here`s the gravity from greatest to least:

Jupiter

Saturn

Uranus

Neptune

Earth

Venus

Mars

Mercury

No, there is no "anti-gravity button" in a spaceship. Spacecraft can create the sensation of weightlessness by achieving a state of free fall around a planet or other celestial body, but true anti-gravity technology does not currently exist.

Nothing, gravity affects everything in the universe every yocto-second. You cant come up with a non example. Even anti-gravity is an example of gravity since your just reversing the pull of gravity to a push.

The strength of gravity weakens as distance increases between objects. This is described by the inverse square law, which states that the force of gravity is inversely proportional to the square of the distance between two objects. This means that the farther apart two objects are, the weaker the gravitational force between them.

Gravity causes things to fall to the ground. I believe it can push or pull things to the ground, to the center of the magnetized earth.

Gravity is important in our lives because it keeps us and everything else on Earth grounded. It causes objects to fall towards the ground and gives us our sense of weight. Without gravity, our bodies would not be able to function properly and many aspects of our daily lives would be significantly impacted.

No, the center of gravity of an irregularly shaped object does not have to be located inside the object. The center of gravity is the point where the weight of the object is concentrated, and it can be located both inside and outside the object depending on its shape and distribution of mass.

One answer is that it is in free-fall in a vacuum (to eliminate atmospheric drag). Another answer is that it is in orbit around another body. The object could be in inter-stellar space, essentially experiencing the balanced gravitational force of "everything". If you eliminate the "middle of space" solution, the object would have to be in a state of acceleration.

A seagull drops a clam while flying over a beach.

Gravitational force is important because it is responsible for keeping planets in orbit around the sun, objects on the Earth's surface, and for the formation of galaxies and stars. It also plays a critical role in our understanding of the structure of the universe and the motion of celestial bodies. Additionally, it is involved in phenomena like tides, the movement of ocean currents, and the behavior of objects in free fall.

A kite is able to defy gravity due to the lift generated by the wind when it flows over the kite's surface. The shape and angle of the kite create an area of low pressure above it and high pressure below it, causing it to be pushed upwards. This lift force counters the gravitational force and allows the kite to fly in the air.

Gravity is not a major influence in the decomposition of a rock, unless the rock

falls off of a cliff.

The main process consists of water seeping into tiny cracks in the rock, then

expanding as it freezes.

Well, if you want to stretch it, I guess you could give gravity the credit for making

the water seep into the cracks.

In a vacuum, one gallon of water would still weigh approximately 8.34 pounds, as the weight of an object is determined by its mass and the force of gravity acting upon it, which is consistent regardless of the presence of air or other elements in a vacuum.

No, horizontal speed does not affect gravity. Gravity acts vertically and is the same for all objects regardless of their horizontal speed. However, horizontal speed can affect the trajectory of an object's motion in relation to gravity.

it depends on acceleration due to gravity as f=mg, when acceleration due to gravity increases the force acting also increases.when force acting increases it cancels the upward thrust(buoyant force)so the body sinks in the liquid.

Gravity causes water to flow downhill, turning the water wheel in the process. The weight of the water creates potential energy, which is converted into kinetic energy as the water falls onto the buckets of the wheel, causing it to rotate.

When you say "high", I'm guessing you mean "above the Earth's surface". If that's true,

then things weigh almost exactly the same up there as they do when they're down on

the ground.

The distance that affects the forces of gravity is the distance between the center of you

and the center of the Earth. That distance doesn't change much when you move up 40 feet.

The magnitude of acceleration due to gravity in space is approximately 9.81 m/s^2, the same as on Earth's surface. This value is a standard convention used in many calculations unless a specific celestial body or location in space is specified.

The only identical feature shared by gravity and mass is the letter 'a' .

The only other possible respect in which they are at all similar is the

fact that they both arise during the discussion of the law and effects

of gravity.

You would definitely have to come across with some serious change before

you could take that baby home with you. In fact, nobody has ever done it yet.

No zero-gravity machine exists now, or has ever yet existed, and nobody has

even come up with a description yet of the science or the technology to do it.
