Electric phenomena occur even in neutral matter because the forces act on the individual chargedconstituents. The electric force in particular is responsible for most of the physical and chemical properties ofatomsandmolecules. It is enormously strong compared withgravity. For example, the absence of ...
The electromotive force or EMF is the electric force produced by the conversion of any form of energy into electric energy. The EMF is a quantity that is present in the explanations of the behavior of electrochemical cells and electromagnetic induction. For example, in the case of a simple el...
Because of this force, water from the faucet always flows downward. Electrostatic Force The electrostatic force is an attractive and repulsive force that exists between particles due to their electric charges. Coulomb’s force is another name for it. Magnetic Force Magnetic force is defined as ...
EMF can be stated as the work done per unit of charge and the SI unit of Electromotive force is Volt. Learn more about the difference between electromotive force and potential difference and dimension of electromotive force here.
How do the gravitational force and the electric force compare? What does a force acting on an object do to that object's motion? What does net force mean? How does surface area affect the acceleration of an object? How does Newton's concept of inertia help us understand why massiv...
This concept can be confusing when first introduced. Looking at the formula for Coulomb’s Law below can help you visualize the relationship between charge and distance, and how this influences the electrostatic force (electrostatic force is the electric force between charged bodies at rest. This ...
An electric field is a region of space around an electrically charged particle or object in which an electric charge would feel force.
To understand electricity, you must understand the electric force and what will happen to charges in the presence of an electric field. What forces will the charge feel? How will it move as a result? A related concept is electric potential, which becomes particularly useful when you talk abou...
This acceleration definition says that acceleration and force are, in fact, the same thing. When the force changes, acceleration changes too, but the magnitude of its change depends on the mass of an object (see our magnitude of acceleration calculator for more details). This is not true in...
