Gravity

weight = Force of gravity

Force= Mass x acceleration

so Force of gravity = Mass x -9.81

that's -9.81 is acceleration in relation to the force on earth. and its negative because gravity pulls things down in a negative direction towards earth.

mass= weight in kg

acceleration= -9.81 m/s^2 on earth

force = is how much gravity pulls on the object and its in Newton's.

how this is what you wanted

The main force acting on a frictionless air puck moving in a straight line across a table is inertia, which keeps the puck in motion. Additionally, there may be forces like gravity and normal force acting on the puck, but these forces do not affect its horizontal motion since the table is assumed to be horizontal.

Sort of...any body of mass exerts its own gravitational pull (the Suns gravitational pull keeps Earth in its orbit, while the Earth's gravitational pull keeps the Moon in its orbit - and us on the surface). Even Humans, dogs, turtles and snails exert some gravitational influence on their surroundings - but in such a low strength as to not have any noticable impact on the immediate surroundings.

At any given distance, the object with the greatest mass also has the greatest gravitational force. That's the Sun. The Sun also has the largest surface gravity.

No. The stars are much too far away for the Earth's existence

to have any measurable effect on them.

Sir Isaac Newton

Venus' atmosphere is much denser and primarily composed of carbon dioxide, with very little oxygen. Its atmosphere exerts a much higher pressure compared to Earth's atmosphere. Venus has a slightly weaker gravitational pull than Earth, with a surface gravity of about 91% of Earth's gravity.

Yes, gravity affects all things in the universe that have mass (and even some things that don't, like light.)

So sadly, as much fun as it would be to fly, your body is not exempt from gravity.

If the mass of the Earth were to increase, your weight might go up. Or it might not, depending on how the new mass was distributed. If the diameter of the Earth also increased, then you might be enough farther away from the increased mass that your apparent weight would be the same or even go down.

In order to increase the mass of the Earth by enough to make a real difference, the Earth would need to get new mass by colliding with a large asteroid or another planet. In that case, your increased weight would be the least of your worries, since we would all be dead.

If it happened in a moment, I think the moon's orbit would become much more eccentric (elliptical) than it is now.

the moon's compostition is made of rocky material such as rocka and a lot of dust

The theory that Einstein developed which pertains to gravity is called general relativity.

The only force acting on the object (let's say a cart) that is released at a certain inclination (30 degrees) is gravity.

If we follow the formulas:

Fgx=mgSinO

Fnet=ma

Fgx=Fnet

Therefore:

mgSinO=ma

and you can simplify this formula to: gSinO=a

m= mass

g= gravitational force (9.8m/s^2)

SinO= sin of angle (Sin30 degrees)

a=acceleration

We cannot measure gravitational forces. Instead, we have to calculate it based on values we are given. The SI unit is N/kg or m/s2 (acceleration), depending on the units given. On Earth, the gravitational force is generalized as 10m/s2 or 10N/kg (to 1 decimal place, it is 9.8 for both).

Because it's the ratio of two densities ... the density of the substance of interest

to the density of water.

In any ratio, the units of both quantities are the same, so the ratio winds up being

a dimensionless number.

Under the Sun's gravity a planet follows an elliptical orbit that conforms to Kepler's laws of planetary motion. This was discovered at the end of the 1600s by Isaac Newton.

Relative to the Earth, any planet with less mass density or volume. If a planet is smaller in all of these respects gravity will decrease. a lot of times with only two and very occasionally with only one. the planets in our solar system that do are venus mars and mercury.

A galaxy.

We live in one corner of a galaxy that we have named the "Milky Way" galaxy. It is thought to contain anywhere from 200 to perhaps 400 billion stars.

The grouping of billions of stars, gas, and dust into a physically metastable rotating state by gravity is, by definition, a galaxy.

Gravity is both good and bad. It helps us to drink water, eat food. We are able to stay on the ground because of gravity. Without gravity we will not be able to stay alive. The disadvantage is that it opposes the upward motion of any object.So gravity is both good and bad.

There are several causes for man-made space debris.

The first is discarded parts from launched spacecraft and rockets. These can be entire burned-out upper stages, pieces that have come off during operation or stage separation like bolts, rivets, pieces of metal/plastic/insulation foam, paint chips etc.

The second are spacecraft themselves: satellites that have reached the end of their useful life because they've suffered from a critical failure or from degradation that limits their capabilities below useful, or because they simply ran out of fuel for station-keeping.

The last part is debris created by collisions of orbiting bodies, which can be natural micrometorites, space junk from one of the first two categories or active spaceraft colliding with each other. One example of this would be the satellite collision on February 10, 2009, when a decomissioned Russian military satellite hit an Iridium communications satellite, destroying both.

Yes, but it is much less than on Earth. If you weigh 150 pounds on Earth you would weigh just 56.5 pounds on Mars. The specifics of the gravity on Mars is tjat it is 62% lower to be more precise. That means that Martian gravity is 38% of Earth's.

Gravity (as we know it) was discovered by accident by Isaac Newton when he was sitting under an apple tree, then all of a sudden an apple hit him on the head which he then proposed the theory of Gravity based on what happen and coined, "What goes up, must come down".
An apple fell on Newton's head and he somehow drew observations and inferences.

Wind can carry abrasive particles which weather rocks . trees can be uprooted by wind, causing the rocks at their roots to fracture. wind can create waves which can fracture or exploit an existing...

Water can chemically weather rocks by dissolving minerals, water can also physically weather rocks by fracturing them by hydraulic pressure or frost wedging.

Sir Isaac Newton is the scientist credited with formulating the law of gravity. His work on gravity and laws of motion were published in his book "Philosophiæ Naturalis Principia Mathematica" in 1687.
