Gravity

With zero gravity, our muscles will begin to lose strength because it would not require as much effort to move. Our muscles will deteriorate to the point where we cannot walk, or even move.

24 hours has no significance to an orbiting satellite.

The only possible connection I can think of might be a case where the ground

controllers responsible for that satellite are on a normal Earthly human schedule,

so that the individuals in contact with the satellite rotate on a 24-hour basis.

-- Look at the formulas you use in order to calculate the mechanical advantage

of any device.

-- If the force of gravity or the weight of any part of the machine appears

in any of those formulas, then the value of the formula depends on the local

gravitational environment, and it depends on which planet the machine is on.

-- If neither of them does, then it doesn't.

Gravity is a property of a mass. Even you generate your own gravity field, though it is too small to be simply detected. So, as long as the mass exists, gravity will exist.

In the 18th century, an experiment was made to determine the mass of the Earth. For this, the investigators measured the mass of a small mountain named Schiehallion in Perthshire. This experiment measured the deflection induced in a pendulum by the mass of this mountain. Measured on opposite sides of course, and consisted of measuring the apparent position (astronomical angle) of some stars. The difference between the two sets of measurements was due to the gravitation attraction of the mountain.

16.55% as strong on the surface.

The sun's gravity has a number of effects on the planets. Primarily, the sun's gravity is what sets the orbits of the 9 planets. With one revolution around the sun equaling a solar year (365.25 days on earth). Planets closer to the sun orbit the sun at higher speeds due the sun's gravity being stronger at short distances (Gravity decreases exponentially as distance increases from an object)

The sun's gravity also has major tidal effects on the planets. High and low tides cycles on earth are partially a function of differences in the sun's gravity on different portions of the earth. The sun's gravity pulls slightly more on the side of the earth facing the sun, causing fluids to bulge toward that side resulting in a high tide cycle. On Mercury, where the sun's gravity is much stronger, tidal forces are powerful enough to alter solid rock and effect the planets landscape.

Gravity can be found everywhere on Planet Earth, the force that keeps us on the ground and doesn't allow us to fly is called gravity.

Mainly because the moon has only about 1/80 as much mass as Earth has.

True, the moon is considerably smaller than the Earth, allowing you to get

closer to its center of mass. But not close enough to compensate entirely

for the difference in mass.

The front wheel is still in contact with the ground. As the rear wheel is pushing the bike forward, the fron wheel doesn't have much choice, either roll or slide. And usually it'll roll.

When you peddle the chain spins round and pushes then u stop peddling but your back well is still moving so that makes your front well move wen your not pedaling

-- An artificial satellite can be operated and observed in a 'polar' orbit, in which

it eventually overpasses every point on Earth, or in any other desired orbit. The

moon's orbit is inclined about 5 degrees to the plane of the ecliptic, which is a

nice orbit, but that's where it stays. So there's a full 62-degree 'cap' around both

the north and south poles, where the moon can never be overhead.

-- An artificial satellite can be operated and observed in an orbit with any desired

eccentricity, and the eccentricity can be controlled and modified at will. The moon's

orbit has a mean eccentricity of only 0.055, and the orbit has many irregularities and

perturbations, which have been studied for many years.

-- For each revolution of the Moon, the Earth rotates inside the Moon's orbit 27.32 times.

The orbit of an artificial satellite can be adjusted so that for each revolution, the Earth

rotates within the satellite's orbit any number of times, from zero and on up.

-- Since the mass of any artificial satellite is so much less than the mass of the

moon, and since most artificial satellites spend most of their time nearer to Earth

than the Moon is, small local irregularities in the shape of the Earth's gravitational

field have a much greater influence on the orbits of the artificial ones.

They orbit around their common centre of gravity, the orbital radius and velocity

of both (centripital force) is exactly enough to overcome the force of gravity between them.

Strictly speaking, it does not. However, the moon does have a greater influence on the tides. Tides are not simply the result of the Moon's gravity. Rather, they occur because the strength of gravity decreases with distance, which means that the moon exerts a stronger gravitational pull on the water on the side facing it than it does at the average point on Earth. Such effects are called tidal forces.

Gravity from an object is directly proportional to its mass and inversely proportional to the square of the distance. This means if you double the mass you double the gravity. If you double the distance, gravity is reduce to 1/4 the original value. If yo triple your distance, gravity is reduced to 1/9 and so on.

Tidal forces are also directly proportional to mass but are inversely proportional to the cube of the distance, so if you double your distance you reduce tidal forces to 1/8. If you triple the distance, you reduce them to 1/27.

So let's do the math. The sun is about 27 million (27,000,000) times the mass of the moon and about 390 times farther away from Earth than the moon is.

First, to calculate the ratio of gravitational force:

27,000,000/(390^2) ≈ 27,000,000/152000 ≈ 178.

So the sun's gravity exerts nearly 180 times more force on Earth than the moon's gravity does.

However if we calculate the ratio of tidal forces

27,000,000/(390^3) ≈ 27,000,000/59,300,000 ≈ 0.455.

So the moon's tidal forces on the Earth are a little more than twice those exerted by the sun.

Well mass is unchanging, so lets say its 100kg (rough estimate), it would still be 100kg on earth, it will still be 100kg in Space and on the Moon.

Weight however will change. To workout weight you use this equation --> WEIGHT = GRAVITY x MASS, so Earth has a gravitational pull of 10N/kg which would mean its weight on earth was 1000N. Space has no gravitational pull, so it would weigh nothing in Space. And the moon has a gravitational pull of about 1.7N/kg, so it would weigh 170N on the Moon! Hope this helped

Usually, large size= large mass. The more mass you have the greater the gravity, but it also depends on how much mass is in a certain amount of space. For example if a large amount of mass spread over a large area the gravity will be less than if all that mass was condensed into a single point.

The sun's gravity keeps the earth and the other planets in orbit around it

Isaac Newton

Earth gravity powers anything that falls, doing work on it equal to its weight

multiplied by the distance it falls, and giving it that much kinetic energy.

The acceleration of gravity on the surface of Mercury, and therefore

the weight of any mass located there, is roughly 37.7% of what it is

on Earth's surface.

Yes. Everything has gravity. Larger and denser objects have more gravity than smaller objects that are less dense.
