Gravity

One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

If the earth's gravity is pulling on you are you pulling on the earth?

User Avatar

Asked by Wiki User

YES!!!

There is a gravitational attraction between any two bodies/masses.

However because your mass is so small compared to the Earth's mass we only feel that attraction as a one - way force.

It has been calculated that two emptysuper=tankers (100,000 tons each) moored alongside each other, with 3 to 4 feet of fender distance betwen, has a gravitational attraction of 1 lb(pound).

Sir Isaac Newton, who gave up the Laws of Universal Dynamics (gravity) , when the apple fell on his head, perceived that not only did the apple fall to Earth, but the Earth , infinitesimally, fell towards the apple.

What is the force with which gravity pulls on objects that are close to earth?

User Avatar

Asked by Wiki User

The force with which gravity pulls on objects close to Earth is approximately 9.8 meters per second squared, often rounded to 10 m/s^2 for simplicity. This force is what gives things weight and causes them to fall to the ground when dropped.

What does gravity have to do with tornadoes?

User Avatar

Asked by Wiki User

Gravity plays a role in the formation and behavior of tornadoes by influencing the movement of air masses and temperatures, which are key factors in tornado development. As warm air rises and cold air sinks due to gravity, it can create the necessary conditions for the rotation and intensification of a tornado.

Where the sun gets its gravity?

User Avatar

Asked by Wiki User

The sun's gravity comes from the mass of the sun itself. Gravity is a fundamental force that arises whenever there is mass or energy in the universe, and it is essential for holding celestial bodies like the sun together and governing their orbits.

How fast must an object go to leave a planets gravity?

User Avatar

Asked by Wiki User

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.

What important star is in the gravity?

User Avatar

Asked by Wiki User

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.

When do you see gravity in action?

User Avatar

Asked by Wiki User

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.

Does Kepler 22-b have gravity?

User Avatar

Asked by Wiki User

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.

What is the meaning of zero air void?

User Avatar

Asked by Wiki User

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.

How does gravity keep objects in motion around the sun?

User Avatar

Asked by Wiki User

Gravity is the force of attraction between objects with mass. In the case of objects in motion around the Sun, the gravitational pull of the Sun keeps them in their orbits. The combination of the object's velocity and the gravitational force between the object and the Sun results in a stable orbit.

Does the sun have less gravity than the moon?

User Avatar

Asked by Wiki User

No, the sun has much stronger gravity than the moon. The gravity of an object is determined by its mass, with the sun being much larger and more massive than the moon.

What is the earth's centripetal force?

User Avatar

Asked by Wiki User

The Earth's centripetal force is provided by the gravitational pull of the Sun, which keeps the Earth in orbit around it. This force is balanced by the Earth's inertia, resulting in a stable orbit. The centripetal force is necessary to maintain the Earth's circular path around the Sun.

What is Newton's derivation of Kepler's third law an example of?

User Avatar

Asked by Wiki User

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.

What is the relative surface gravity of Mars to Earth?

User Avatar

Asked by Wiki User

The relative surface gravity of Mars is about 0.38 times that of Earth. This means that Mars has less gravity pulling objects towards its surface compared to Earth.

Why do the Moon's gravity have a greater effect on earths ocean tides than the suns gravity?

User Avatar

Asked by Wiki User

The Moon is closer to Earth than the Sun, so its gravitational pull on Earth's ocean water is much stronger. Also, the Moon's gravitational force varies more across Earth due to its closer proximity, creating larger tidal bulges. Additionally, the Moon's gravitational force is in direct alignment with Earth's axis, contributing to the stronger tidal effects compared to the Sun.

What if there was gravity in space?

Asked by MohamedAzizZezo

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.

Why is there no gravity in outter space?

User Avatar

Asked by Wiki User

Outer space is not completely devoid of gravity; there is still gravity present in space but it is much weaker compared to that on Earth. The sensation of weightlessness experienced in space is due to the free fall of objects in orbit around a planet. Objects in space appear weightless because they are in a continuous state of falling towards the center of the planet without ever reaching it.

Where did the theory of gravity come from?

User Avatar

Asked by Wiki User

The theory of gravity was first proposed by Sir Isaac Newton in the late 17th century. Through his observations and mathematical calculations, Newton formulated the law of universal gravitation which described how all objects with mass are attracted to each other. His theory revolutionized our understanding of the physical world and laid the foundation for modern physics.

Is the critical velocity equal to orbital velocity of satellite?
