Is gravity caused due to magnetic field of earth or due to the mass of earth?
Gravity is mainly caused by the mass of Earth. The magnetic field of Earth plays a minimal role in the force of gravity experienced at the surface. Gravity is a fundamental force of attraction between all masses, and the larger the mass, the stronger the gravitational pull.
What makes gravity increase?
Gravity increases as mass or density increases. In other words, the more mass an object has, the more gravitational force it exerts. For example, the gravity on Earth is stronger than the gravity on the Moon because Earth has more mass.
Does earth the moon and sun have gravity?
Yes, they have gravity. In fact, anything that has mass will have a gravitational force - the more mass a body has, the more gravitational force it will exert.
What effect do mass and distance have on the force of gravity?
The force of gravity between two objects is directly proportional to their masses - greater mass means stronger gravitational force. The force of gravity is inversely proportional to the square of the distance between the objects - greater distance means weaker gravitational force.
How does gravity effect weight of an object?
As somebody previously said, gravity is directly proportional to weight. As gravity increases, weight increases. The simplest way to define gravity is the downward force that holds objects down. eg. you can sit in your computer chair due to gravity. It is holding you down. You would otherwise float as in space where there is no gravity. If that gravity force becomes greater, ie. there is more force pushing you down, you will weigh more. It pushes down on you more.
Is gravity the second strongest force in the universe?
Gravity is actually the weakest of the four fundamental forces in the universe, with the strong nuclear force, weak nuclear force, and electromagnetic force being stronger. Gravity is responsible for the attraction between masses on a macroscopic scale, but on the atomic and subatomic levels, the other forces play more significant roles.
Can electricity be a stronger than the force of gravity?
Electricity and gravity are two different fundamental forces in nature, with gravity being much weaker than the electromagnetic force. In situations involving charged particles, electromagnetic forces can be stronger than the force of gravity. However, at larger scales (e.g., planetary bodies), gravity dominates due to its long-range nature and cumulative effect.
Is gravity the strongest force in the world?
Gravity is a notoriously weak force! Consider this; a fridge magnet using the electromagnetic force can overcome the gravity OF THE ENTIRE PLANET! It is a bit difficult to directly compare two different forces, but the gravitational attraction between two electrons is about 40(!!) orders of magnitude smaller than the electromagnetic repulsion. The reason for this is not yet known, it is hoped that a quantum version of the general theory of relativity might shed more light on this in the future, but such a quantum version has not been discovered at present.
How are gravitational and electromagnetic force different?
There are quite some differences. The most obvious one is that electromagnetism acts on charges, while gravity acts on energy (remember energy and mass are the same thing in relativity). There are also two types of electric charges, positive and negative, while there is just one gravitational 'charge'. The gravitational force is also much much weaker than the electromagnetic force; a common fridge magnet can overcome the gravitational attraction of the entire Earth! Gravity also allows for a geometric explanation involving curves and warps in spacetime whilst electromagnetism does not. There are also more complicated differences. For example the electromagnetic force is mediated by a spin-1 particle called the photon. Gravity on the other hand is expected to be mediated by a spin-2 particle called a graviton (I say expected because the graviton has not yet been observed, mainly because gravity is so weak). On a more technical note forces in quantum gravity are related to symmetries of nature. The symmetry group of the electromagnetic force is U(1) whilst the one of gravity is SO(3,1). Even more technical: because U(1) is an abelian group photons are themselves chargeless, but SO(3,1) is not an abelian group so the graviton can couple to itself (i.e. self-interaction). This is reasonable because the graviton carries energy, and gravity couples to energy.
How come people dont get pulled into each other by gravity?
The simple answer is that gravity is actually an extremely weak force. A common fridge magnet can overcome the attraction of the entire Earth! Gravity only becomes powerful for very heavy objects like planets and stars. Everyday objects as well as people are simply not massive enough to provide much of a force. The reason why gravity (though weak) is the dominant force at long range is that gravity only adds to itself; adding more mass only makes it stronger and you cannot really stop gravity. Compare this to the electromagnetic force; although it is much more powerful it acts on charges, and both positive and negative charges exist. Therefore you can stop the electromagnetic force by negating a charge by adding the opposite charge to it. The Universe is largely electrically neutral, so long range electromagnetic forces do not appear.
Which force is greater gravitational force or electromagnetic force?
Electromagnetic force is greater because in microscopic theories usually gravitational force is neglected and we can attract a pin from the ground by electro magnet easily yet smaller in size, both acts at the vast range but electromagnetic force is far more greater then gravitational.
What variables do magnetic forces rely on?
Magnetic forces are like gravity, only in place of mass, the force between two magnets is directly proportional to the product of the charges, and inversely proportional to the square of the distance between them. There are also maxwell's equations which are much more complicated, but better explain the activity of electromagnetic charges on a more universal scale.
Who discovered the four forces of nature?
The four fundamental forces of nature are gravity, electromagnetic force, weak nuclear force, and strong nuclear force. These forces were discovered and explained by different scientists throughout history: Isaac Newton for gravity, James Clerk Maxwell for electromagnetic force, Enrico Fermi for weak nuclear force, and Hideki Yukawa for strong nuclear force.
Does gravity have more force in dark or light?
The amount of light doesn't effect the force of gravity.
What does gravity mean in space?
"Gravity" is a force between any two objects. This specific force depends on the masses (more mass --> more force), and on the distance between the objects (more distance --> less force).
What force is more powerful than gravity?
Applicably speaking: The downward force out of the bottom of a set of Saturn 5 Rockets. Theoretically speaking: Anything that can overcome the force of g. Out of the three fundamental forces, both the Electromagnetic and the Nuclear force are more powerful than the Gravitational force.
Is gravity caused due to magnetic field of earth or due to the mass of earth?
Gravity is mainly caused by the mass of Earth. The magnetic field of Earth plays a minimal role in the force of gravity experienced at the surface. Gravity is a fundamental force of attraction between all masses, and the larger the mass, the stronger the gravitational pull.
