Gravity

When gravity acts on the mass of an object, it causes the object to have weight. Weight is the force of gravity acting on an object's mass, and it gives the object its downward push or pull towards the Earth's center.

The buoyant force acting on an object in a fluid is determined by the volume of the object displaced by the fluid. This volume is known as the displaced fluid volume, and it depends on the shape and size of the object in relation to the fluid.

The center of gravity of a person is exactly the same as it is for any other mass object:

It's the unique point where the weighted relative position of the distributed mass

sums to zero. Another way to understand it is: the point where the total mass

appears to be concentrated when observing the effects of external mechanical

forces acting on the object.

A person's center of gravity is located roughly behind his belly button, in the center

of the circle formed by his belt. On the average, it's a bit higher than that for men,

and a bit lower than that for women.

That depends on where it is. If it's on the surface of the Earth, then the forces of

gravity in both directions between the block and the Earth are about 9.807 newtons

(2.204 pounds). But if you take the block to the moon's surface, for example, then the

forces of gravity in both directions between the block and the Moon are about

1.62 newtons (5.84 ounces).

If the block is on or near the Earth's surface,

it weighs 9.807 newtons (2.205 pounds).

To create a no-gravity potion, you would need to include ingredients that counteract the effects of gravity, such as levitation potions or anti-gravity compounds. These may include magical elements or fictional substances based on the rules of the fantasy world. Be sure to establish clear rules and limitations for how this potion works within your story or game.

The only place where there is no gravity is in space, infinitely far from any mass.

To create the conditions that your body interprets as zero gravity, choose one of these:

-- Jump from an airplane or balloon. Do whatever skydivers do to minimize your

air resistance and fall as fast as possible. That puts you close to zero gravity,

but not exactly.

-- For brief periods of zero gravity, like 30 seconds at a time, take the training

and get a ride on NASA's "Vomit Comet" airplane.

-- Get into Earth orbit somehow.

Yes, potential energy can be related to gravity. In a gravitational field, an object raised above the ground will have gravitational potential energy due to its position relative to the Earth's surface. This potential energy can be converted into kinetic energy as the object falls, following the principle of conservation of energy.

Gravity causes small objects to be pulled towards larger objects, such as the Earth. The force of gravity is directly proportional to the mass of the objects and the distance between them, so small objects experience a weaker gravitational force compared to larger ones. This force is what gives small objects weight and keeps them grounded.

FSL stands for Free Surface Level. In a gravity canal, the FSL is the level of the water surface that is free to interact with the atmosphere and not confined by any structure. It indicates the height at which water is flowing in the canal.

The measure of the pull of gravity on an object is its weight, which is determined by the mass of the object and the acceleration due to gravity. The acceleration due to gravity varies on different planets, so the weight of an object will change if it is on a planet other than Earth.

The force of gravity between two objects is determined by their masses and the distance between their centers. The larger the masses of the objects and the smaller the distance between them, the greater the force of gravity.

A quarter and and a pencils have little air friction and would not observed to fall at different velocity in normal classroom condition. It will be observed to fall to the ground at the same time.

If you increase the mass, you increase the gravitational force proportionally.

If you increase the distance between two masses, you decrease the gravitational force between them by and amount proportional to the square of the distance.

no a body can,t be rotate about its centre of gravity

Plants can contribute to weathering by a tree growing in the cracks of a rock then its roots will eventually run out of room therefor it pushes steadily against the rock until it breaks and so on.

It is very well known that Issac Newton was said to be the first to discover gravity while walking through his estate one day and saw an apple fall from a tree. He then asked, "If an apple falls from a tree, does the moon also fall?" He then created calculus, which was originally created to calculate the speed of a falling moon. So in short, Issac Newton.

Gravity acts as a centripetal force when it pulls an object towards the center of rotation in a circular motion, keeping the object moving in a curved path instead of a straight line. This allows the object to continually change direction without breaking away from the circular path, achieving dynamic equilibrium.

Force equals mass times acceleration, if you are sitting at rest you are not accelerating, so your acceleration is zero.

The force is your mass times zero, 75 kg x 0 ms-2= 0 newtons.

If the force is zero, this means the force of gravity pulling you down is cancelled out by the force of the chair pushing you up.

So the forces are balanced.

Gravity is both a theory and a law. The theory of gravity, proposed by Isaac Newton, explains how objects with mass attract each other. The law of gravity, also known as the law of universal gravitation, quantifies this force of attraction between objects with mass.

Weight is what we call the amount of the gravitational force between the Earth

and an object on the surface of the Earth.

It works both ways. Your weight on the Earth is also the Earth's weight on you.

To calculate the effect of gravity on weight, you multiply an object's mass by the acceleration due to gravity. The formula is W = m * g, where W is weight, m is mass, and g is the acceleration due to gravity (9.81 m/s^2 on Earth). The result will be in units of force (e.g. Newtons).

The value of 3g would be three times the acceleration due to gravity (g). On Earth, the average value of g is approximately 9.81 m/s^2, so 3g would be 3 * 9.81 = 29.43 m/s^2.

If the mass of one or both objects were increased by a factor of four, the force of gravity between them would be four times greater. The force of gravity is directly proportional to the product of the masses of the two objects.
