Gravity

Gravity is proportional to the product of the masses, and inversely proportional

to the square of the distance. The gravity constant is simply the proportionality

constant.

If you're calculating with all SI units, then the universal gravitational constant is

6.67 x 10-11newton-meter2/kilogram2

As you get further away from Earth, the gravitational forces between you and

Earth decrease. But the gravitational forces between you and something else

might increase, like between you and the moon, or between you and the sun.

The forces of gravity between two masses are always forces of attraction.

As far as we know now, gravity always draws the two masses towards each

other, and never pushes them apart.

There are 5 consonants in the word "gravity" - "g", "r", "v", "t", and "y".

Newton's law of universal gravitation states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This law helps us understand how the force of gravity between objects changes as their masses change or as they move closer or farther apart.

The center of gravity of the human body is typically located around the pelvis region, specifically near the sacrum. This point is important for maintaining balance and stability during various movements. It varies slightly depending on body composition and posture.

Earth's gravity is the force that objects experience due to the planet's mass. The acceleration due to gravity on Earth is approximately 9.8 m/s^2. This means that objects on Earth experience a gravitational force that is about 9.8 times stronger than in space.

Mass is a measure of the amount of matter in an object, weight is the force of gravity acting on an object due to its mass, and gravity is the natural force of attraction between objects with mass. In simple terms, mass is what an object is made of, weight is the force with which it is pulled down by gravity, and gravity is what causes that force.

-- Gravity causes the vertical component of projectile motion to vary according to

the local acceleration of gravity.

-- Gravity has no effect at all on the horizontal component of projectile motion.

Electic Force At A Distance By Jhon

Yes, light is affected by gravity. According to Einstein's theory of general relativity, gravity can bend the path of light rays, a phenomenon known as gravitational lensing. This effect has been observed in various astronomical observations.

Gravity affects the motion of objects by pulling them towards the center of the Earth. This force causes objects to accelerate as they fall towards the ground. The acceleration due to gravity is a constant value on Earth, which is approximately 9.81 m/s^2.

Speed and acceleration do not directly affect gravity. Gravity is a fundamental force that acts on all objects regardless of their speed or acceleration. However, an object's speed and acceleration can influence its motion within a gravitational field, such as causing it to orbit a larger body or fall towards it at an accelerated rate.

Our lives would be drastically affected if there was no gravity. Without gravity, objects and people would float away into space, making it impossible to perform everyday tasks such as walking, eating, or driving. Our bodies are adapted to living in a gravitational environment, so the absence of gravity would have severe consequences for our health and well-being.

Your weight is determined by the force of gravity acting on you, so it will change if the acceleration due to gravity changes. If the acceleration due to gravity increases, your weight will increase, and if it decreases, your weight will decrease.

Yes. When light bounce off a mirror, that's changing the direction. Reflecting is NOT bending. It bends when it passes in close proximity to a massive object such as a black hole or when it travels into a differing medium where the speed of light varies (for example entering a piece of glass).

The force of gravity acts downwards on a submarine, causing it to sink. Buoyancy, which is the upward force exerted by a fluid that opposes the weight of an immersed object, acts in the opposite direction, helping to keep the submarine afloat or rise back to the surface when necessary by adjusting the density of the water within its ballast tanks. By managing these forces, submarines can control their depth underwater.

The simple answer is: You can't.

But I can propose a way to do it. It may not be perfectly accurate,

but it's bullet-proof and air-tight in principle:

-- Get a board of substantial length, like a piece of shelf material.

Also get a little block of wood, same thickness as the height of the scale.

-- Set the board down level, with one end on the little block, and the

other end on the scale.

-- Stand exactly on the center of the board.

You've created a Class-III lever with a mechanical advantage of 1/2 .

The fulcrum in on the little block, your weight in the center is the effort,

and the load is the end on the scale.

The scale bears 1/2 of your weight.

No. Mass and density are two different measures. An object can have more mass and less density. One pound of water in a gallon space has more mass than 1/2 pound of water in a quart space. The the quart space will be more dense 1/2 pound per quart however than the 1 pound per 4 quarts in the gallon.

No, gravity and magnetism are not examples of contact forces. Contact forces require direct physical contact between objects for interaction to occur, while gravity and magnetism can act at a distance without physical contact.

Gravity is the force of attraction that exists between objects with mass. It is responsible for keeping planets in orbit around the sun and objects grounded on Earth. The strength of gravity depends on the mass of the objects and the distance between them.

Sure, if either of the following conditions is true:

-- The smaller mass started dropping before the larger mass did. As long as

(MsmallVsmall) is equal or greater than (MbigVbig), the smaller mass has equal

or more momentum than the larger one has. But of course, the momentum

of the larger mass catches up as its speed grows.

-- The smaller mass and the larger mass were dropped at exactly the same time,

but on different planets. Then, if the smaller one was dropped in a place where

gravitation is greater, and the greater mass was dropped in a place where

gravitation is less, it's quite possible for the smaller mass to have more

momentum than the larger mass has, at least for a while.

If the acceleration of gravity on the larger planet is at least (larger mass x acceleration of gravity on the smaller planet/smaller mass) or more, then the smaller mass has more momentum than the larger mass has

forever, or as long as they're both freely falling.

The terms "gravitational force" and "force of gravity" are interchangeable and both refer to the same force exerted on objects due to gravity. When an apple is falling, the force of gravity (gravitational force) is indeed acting on it, causing it to accelerate towards the Earth.

The list of choices posted with the question doesn't include anything

that fits that description.

It sounds something like a "star", but in a star, it would be "fusion", not "fission".

It's not known for certain but it is believed to be around 2g/cm3, probably inferred from Pluto which is about the same. The Earth for comparison is 5.5153 g/cm3
