What else can I help you with?
The gravitational force is always attractive while the electric force is both attractive and repulsive. what accounts for this difference?
All mass has the same sign, while electric charge can be either positive or negative.
Is gravitational force a non-contact force?
no
Force that causes an object o move in the same direction as the force is?
gravitational pull/force
What is gavitational force?
gravitational force is a basic force of nature, it presents everywhere and at all time. The gravitational force acts between any 2 masses in the universe and pulls them toward each other .It is the force that pulls objects toward earth.
Difference between electric and gravitational forces?
Gravitation is much weaker, and it always attracts.add Gravity can be considered as a property of matter, or at least of the curvature of space-time. Gravitation Wavesare believed to travel at the velocity of light. Wikipedia has an article "speed of gravity".Various scientists are attempting to detect Gravitation Waves from rotating stellar objects, but so far without success. Forces in Newtonian Physics propagate at infinite velocity, hence the interest in this definitive experiment.Have a crack at the Introduction paragraph of Gravitation Waves above. And Gravitons.Definitely one of the Fun Parts of Physics.{not to be confused with Gravity Waves, which are Earth-bound waves on the ocean and similar.}Electric forces are due to the presence of electrons. If the electrons are moving, you have an electric current, and this can generate a magnetic field.[Even if there is no electric current, the electrons actually spin in their natural state, and if a number of electrons have a similar spin, then you may have a permanent magnet.] [Posit. Do all the electrons in a current have similar spin?].One may establish a surplus number of electrons on an insulating surface, and this static electric field will repel a similar field.
Is gravitational force attractive or repulsive?
Gravitational force is always attractive, meaning that it always pulls objects towards each other due to their mass.
What is the disadvantage of gravitational force?
One disadvantage of gravitational force is that it becomes weaker as distance between objects increases, leading to a decrease in its effect over long distances. Additionally, gravitational force is always attractive and cannot be repulsive, which limits the range of interactions it can facilitate.
How is the gravitational force like a magnetic force?
Gravitational force and magnetic force both act at a distance without direct contact. They both follow an inverse square law, meaning the strength decreases with distance squared. However, gravitational force is always attractive between masses, while magnetic force can be attractive or repulsive between charges.
Why does an electric force stronger than gravitational force?
The electric force is stronger than the gravitational force because electric charges can be positive or negative, allowing for attractive and repulsive interactions, while gravity is always attractive. Additionally, the strength of the electric force is determined by the charge of the particles involved, which can be much larger than the masses involved in gravitational interactions.
This is a force where objects are attracted or repelled to one another?
Gravitational force exists between masses. Gravitational force is only of attractive. No repulsive gravitational force has been found so far. But in electrostatics and magnetism, the force between electric charges and magnetic poles respectively are of both repulsive and attractive. Nuclear force between the nucleons within the nucleus of the atom is also attractive in nature.
Compared to the electric force the gravitational force between 2 protons is?
The electric force between two protons is much stronger than the gravitational force between them. The electric force is about 10^36 times stronger than the gravitational force at the atomic scale. This is why charged particles interact primarily through electromagnetic forces and not gravitational forces.
The gravitational force is always attractive while the electric force is both attractive and repulsive. what accounts for this difference?
All mass has the same sign, while electric charge can be either positive or negative.
How do the gravitational and electric forces resemble each other how do they differ?
Gravitational and electric forces are similar in that both are inverse square laws with distance, where the force decreases as distance increases. However, gravitational force acts between masses due to gravity, while electric force acts between charged particles due to electrostatic interactions. Gravitational force is always attractive and only has one type, while electric force can be attractive or repulsive and has positive and negative charges.
What is the basic difference between attractive and repulsive forces?
Attractive forces bring objects closer together, such as gravitational attraction between two masses. Repulsive forces push objects apart, like the electrostatic repulsion between two positively charged particles.
What will be the direction of charge if the gravitational force is equal to electrostatic force?
If the gravitational force is equal to the electrostatic force, the direction of the charge will depend on the relative signs of the charges. If the charges are of opposite sign, the direction will be attractive (towards each other), and if the charges are of the same sign, the direction will be repulsive (away from each other).
What the meaning of repulsive?
Serving, or able, to repulse; repellent; as, a repulsive force., Cold; forbidding; offensive; as, repulsive manners.
How is gravity formed?
There's no reason to suspect that there is such a thing as antigravity. As far as we know, all mass has the same "gravitational charge" (mass), and the force is always an attractive force, never a repulsive force. So, sorry, there's no such thing as antigravity.
