Gravity

Gravitational force is a property of mass. Wherever there's mass, there will be

force between it and any other mass. The more mass there is, the greater the

forces will be between it and any other mass. The sun has quite a bit of mass ...

something like 1,989,000,000,000,000,000,000,000,000,000 kilograms of it,

compared to about 84 kilograms in me ... so you can expect quite a bit of force

between the sun and any other mass within a few billion miles of it.

The speed that ab object must travel at to escape a planet's gravity is called escape velocity. This value varies depending on the mass and diameter of the planet. Here are the escape volcities of the eight planets of our solar system.

Mercury: 9,400 mph

Venus: 23,000 mph

Earth: 25,000 mph

Mars: 11,000 mph

Jupiter: 133,000 mph

Saturn: 77,000 mph

Uranus: 48,000 mph

Neptune: 53,000 mph

Note that escape velocity only takes gravity into account and ignores other forces. An object launched from Earth's surface or from any other planet with a substantial atmosphere at escape velocity would be quickly destroyed and slowed down by air resistance.

The most important star in terms of gravitational influence on our solar system is the Sun. Its gravitational pull keeps the planets in orbit around it. Additionally, the interactions between stars in a galaxy are primarily driven by their gravitational forces.

Gravity is always in action, pulling objects towards each other. We see gravity in action when we drop something and it falls to the ground, when the planets orbit around the sun, and when we jump and come back down to the Earth.

Yes, Kepler-22b has gravity. Gravity is present on all celestial bodies with mass, including exoplanets like Kepler-22b. The gravity on Kepler-22b would be weaker than Earth's due to its larger size and lower density.

Zero air void means that the material is completely compacted with no air voids present. This is often desired in construction applications to ensure maximum density and strength of the material. Achieving zero air void can improve the material's durability and performance characteristics.

Gravity, per say, doesn't. It's only a player in the game. With only gravity, things would slowly be sucked into the sun, like a black hole. So that's where the other team, inertia comes in. Inertia is Newton's first law of motion, stating that an object in motion will continue to stay in motion unless another outside force messes with it.

And so we have two major forces, gravity and inertia, pushing on one another. Neither win, and as gravity wants to pull into itself and inertia wants to fly away in a straight line, we get a circular path for the object that most call, an orbit.

No.

Gravity is a function of mass, and the sun's mass is about 27,000,000 times the mass of the moon.

The term "centrifical" is a word without a definition; some would say a non-existent word. It might have the same definition as "ncauvjnscc" or "oioushc" or any other made up babble you chose to imagine. However, the term has been used enough in common parlance as to associate its meaning with either "centripetal" or "centrifugal".

The centripetal force is the force applied to a linearly travelling (straight line) object to make it travel in a curve or to make it rotate about some center point. The force is applied to the object make it move toward that center point.

The centrifugal force is referred to as the opposite force to the centripetal force following Newtons Law of equal and opposite reaction. However, this force is a consequence of the inertia of the object (resistance to the circular motion) and acts on the source of the centripetal force, NOT the object experiencing curved motion.

The centrifugal force is equal, but opposite, the centripetal force.

For instance, a weight on a string attached to an object swung about your head experiences a force applied inward (centripetal force) due to your hand (the center point) applying the force. The string also experiences this force all along its length. Your hand experiences a force applied outward (centrifugal force) due to the weights inertia (resistance to change direction at all points in time as it moves in a circle). The string also experiences this force all along the string. The opposing forces on the string keeps the string in tension. Additionally, your feet share a friction force against the surface you stand on equal to the centripetal force to keep you stationary.

So the question remains: which force did you really mean, centripetal or centrifugal?

Newton's derivation of Kepler's third law is an example of how theoretical physics can be used to explain and validate empirical observations. By applying his law of universal gravitation to Kepler's laws of planetary motion, Newton was able to mathematically derive Kepler's third law, providing a more fundamental understanding of the relationship between a planet's orbital period and its distance from the sun.

Mars has 38% the pull of gravity than th Earth's.

Even though the suns gravitational pull is stronger than the moons and does infact effect the tides slightly, the moon is close enough to pull the tides more than the sun. Its all distance related.

If there was gravity in space, objects would be pulled towards each other, affecting their motion and orbits. This could lead to different interactions between celestial bodies and potentially alter the dynamics of the universe as we know it.

Gravity Destroyer's special move is called the "Black Excalibur." This move allows Gravity Destroyer to unleash a powerful spinning attack, using its weight and momentum to overpower its opponent. It is known for its destructive force and ability to knock out or destabilize opposing Beyblades.

Gravitity presumably appeared at the instant of the Big Bang, along with

all the other laws of Nature and Physics. So it's about 14 billion years old.

Yes, the moon has gravity. Its gravity is about 1/6th that of Earth's, which means objects on the moon weigh much less compared to on Earth. This gravitational force is what keeps the moon in orbit around Earth.

There is gravity everywhere.

-- The force of gravity that you feel is a force between you and another mass.

The Earth is the "other mass" that we're all used to. If there's no major mass

nearby, then there's no force to feel.

-- Even if there is a major mass nearby, you don't feel the gravitational forces

if you're falling freely toward it. In "outer space", you're falling freely or coasting

most of the time, without running your rocket engines. So even if there is some

mass that you're being attracted to, you don't feel the force, because you're falling

freely toward the mass.

Though astronomical observations and theories have been around for thousands of years, the coming together of knowledge that tied down the effects of gravity, is attributed to mainly newton and einstien, though a true explanation of gravity is still elusive.

Apollo 11 overcame Earth's gravity by using a powerful rocket called the Saturn V. The rocket had multiple stages that ignited in sequence to propel the spacecraft into space. Once in space, the spacecraft's speed allowed it to escape Earth's gravitational pull and travel to the Moon.

Though Neptune is approx. 17 * mass of earth, its only 1/3 the density, so the acceleration at the surface radius ends up pretty much the same, though slightly greater @ 11 m/s2 compared to earth @ 9.8 m/s2, but if you stood the same distance from both planets, Neptune's gravity would offer a force 17 times greater.

100 kg would weigh 112 kg on Neptune

Projectile motion and satellite motion both involve an object moving through a gravitational field. However, satellites are in a state of continuous free fall around a celestial body, while projectiles follow a parabolic path with a defined initial velocity and angle. Additionally, satellites have a stable orbit due to their speed and altitude, while projectiles experience a temporary motion before returning to the ground.

Sir Isaac Newton, the English Mathematician and Physicist who created the

theory of gravity that explained the effects of it that we see around us, called

it "Universal Gravitation".

Humans have developed adaptations such as bipedalism, strong musculature, and a well-developed inner ear system to help overcome the force of gravity. These adaptations allow us to walk upright, maintain balance, and resist the pull of gravity on our bodies. Additionally, advancements in technology like transportation and aerospace engineering have provided further means to mitigate the effects of gravity on human activities.

Gravity is the force that keeps Earth in orbit around the Sun. The gravitational pull between the two objects causes Earth to move in a curved path around the Sun, creating the elliptical shape of its orbit. Without gravity, Earth would not be able to stay in its orbit and would drift off into space.
