Gravity

-- 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

Acceleration due to gravity is greater at the surface of the Earth compared to higher altitudes or in outer space. This is because the force of gravity is stronger closer to the center of mass of an object, such as the Earth.

Gravity is more forceful because it has the ability to pull things down and have everything stay on the Earth. Weak nuclear force is clearly weak and can't really pull things down and keep them there. I hope this helped :)

Generally free fall recreates zero G. Air resistance will change things if you're falling like a parachutist.

What the astronauts experience is exactly free fall, but without a strong wind causing terminal velocity as parachutists.

For about 30 seconds at a time, special aircraft can fly in a manner that simulates free fall (also avoiding the wind (at least on the inside of the aircraft).

When gravity acts on large drops of water, the drops become unstable and tend to break apart into smaller drops. This is because the force of gravity exceeds the surface tension that holds the water droplet together, resulting in the droplet stretching and eventually separating into smaller droplets.

No. But it's designed to do its job by taking advantage of air resistance.

No, a magnetic field is not needed to create gravity. Gravity is a fundamental force of nature that exists between all objects with mass, whereas magnetism is a different fundamental force that arises from the motion of electric charges.

That is called gravitational potential energy. When no confusion is possible, it might just be called "potential energy", although there are other types of potential energy, such as the potential energy in an electrical or magnetic field.

It is responsible for keeping the wheels of the car in contact with the ground,

as well as keeping the driver and passengers in contact with their seats if seat-

belts are not used.

There are not many internal mechanical functions in the propulsion system (the motor)

that are left up to gravity.
