The electric force between the negatively charged electrons and the positively charged nucleus in an atom provides the centripetal force needed to keep electrons in orbit. This force balances the tendency of the electrons to move in a straight line due to their inertia, thus maintaining their circular motion around the nucleus.

What causes an electric current to keep moving?
An electric current keeps moving because of the presence of an electric field. The electric field exerts a force on the charged particles (usually electrons) in the conductor, causing them to continue moving. In a closed circuit, the movement of electrons from the negative to the positive terminal of the power source ensures a continuous flow of current.
What provides the centripetal force needed to keep Earth in orbit?
The gravitational force between Earth and the Sun provides the centripetal force needed to keep Earth in orbit. This force keeps Earth moving in a circular path around the Sun.
Why does an object in orbit needs a centripetal force act?
An object in orbit needs a centripetal force to keep it moving in a circular path. Gravity provides this centripetal force, pulling the object towards the center of the orbit. Without this force, the object would continue in a straight line tangent to the orbit.
What is the relationship between the velocity of a circular orbit and the gravitational force acting on an object in that orbit?
The velocity of a circular orbit is directly related to the gravitational force acting on an object in that orbit. As the velocity increases, the gravitational force required to keep the object in orbit also increases. This relationship is governed by Newton's law of universal gravitation.
Why radial force doesn't work on orbit in circular motion?
Radial force in circular motion does not work because the acceleration needed to keep an object moving in a circle is provided by the centripetal force, directed towards the center of the circle. This centripetal force maintains the object's velocity and prevents it from moving in a straight line. Therefore, no additional radial force is required for the object to stay in orbit.

What keeps electrons in the space around a nucleus?
The electrostatic forces between the protons and the electrons keep it in orbit.
What causes electric current to keep moving?
What causes an electric current to keep moving is a steady supply of electrons.

How does Neptune gravity keep Neptune in motion?
No force is necessary to keep a moving object in motion. But if you want it tofollow a curve, such as for example a closed orbit, then that takes force. Theforce that keeps Neptune in its closed orbit is the same force that keeps everyplanet, moon, comet, and asteroid in its own closed orbit around its own centralbody. It's the force of gravity.
How does the centripetal force act on a satellite?
The centripetal force acts towards the center of the circular path followed by the satellite, allowing it to maintain its orbit. In the case of a satellite orbiting Earth, the force of gravity provides the centripetal force required to keep the satellite in its orbit.
Does gravity provide a centripetal force on the moon helping it stay in orbit around the earth?
Yes, gravity is the centripetal force that keeps the Moon in its orbit around the Earth. The gravitational force between the Earth and Moon provides the necessary inward force (centripetal force) to balance the outward inertial force and keep the Moon in a stable orbit.
What describes the electric forces inside a atom?
The electric forces inside an atom are responsible for holding the negatively charged electrons around the positively charged nucleus. These forces keep the electrons in stable orbits and determine the overall structure and behavior of the atom. The electromagnetic force is one of the fundamental forces of nature that governs these interactions.
How does gravity work to keep the solar system?
it uses its force to make the planets orbit the sun.
