Subatomic particles - as well as atoms and molecules which are made up of such particles - have a property called "electric charge". This charge can be positive, negative, or neutral (no net charge). There is a force among such charges; this force is attractive for opposite charges, and repulsive for like charges. In other words, a positive charge and a negative charge attract one another; while two positive charges, or two negative charges, push away from one another.

Electricity is like an avalanche. The electrons of the conductive material jumps from one atom to the next pushing the electron from that atom on to the next one. One of the four fundamental forces, the electromagnetic force manifests itself through the forces between charges (Coulomb's Law) and the magnetic force, both of which are summarized in the Lorentz force law. Fundamentally, both magnetic and electric forces are manifestations of an exchange force involving the exchange of photons. If you're asking what it's measured in, the answer is "Volts".
Potential Difference causes electrons to flow, it is a difference in charge of the particles from one location to the next. Like two masses of air with different densities, the two masses mix to find an equilibrium pressure. Electrons seek to do the same thing, whether around a nucleus or flowing through a wire, they want to travel to find a neutral charge state. They flow in the direction of positive charge to negative charge.
No. Electric force is not a contact force.
This force is the electrical potential.
This is an electromagnetic force of repulsion.
force between charged particles.
Air resistance is a contact force because you are in contact with the air in order to apply that force.
Contact.
Contact forces are forces that can only have an effect on objects that they touch, such as when you contact a box and apply force to move it. you might apply a contact force to bend, tear, stretch, compress, or twist and abject. Tension force, friction force, and elastic force are examples of contact forces.
no
The contact force will keep the ball moving but as the ball goes farther the ball slows down that's were the non contact force comes in it makes the ball not in contact
A non-contact force
A non-contact force
electrostatic force is not a contact force it is force at a distance likely to that of gravitational force.
Electric and gravitational and derivatives of electric force such as Van Der Waals forces.
Magnetic force is a non-contact force. It can also be described as a force of 'Attraction' or 'Repulsion'.
A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar example of a non-contact force is gravity, which confers weight. ... Gravity, the force of attraction that exists among all bodies that have mass.
A spring force is a contact force not a non-contact force.
An electric force is the force on an electric charge or an electrically charged object when immersed in an electric field.
Force can be both contact or non-contact
Magnetic force is a non-contact force.
it uses electric force
Electrostatic Force are non-contact force.
