Electrostatics is the branch of physics that studies slow-moving or stationary electric charges and their interactions. The electrostatic force between two point charges is proportional to their product and inversely proportional to the square of the distance between them, as described by Coulomb's law.
Coulomb's law is an experimental law of physics that calculates the amount of force between two electrically charged particles at rest. It states that the force is proportional to the product of the charges and inversely proportional to the square of the distance between them.
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Learn about the different types of friction, such as dry, fluid, lubricated, skin and internal, and how they affect mechanical energy, wear, and performance.
Static electricity is an imbalance of electric charges within or on the surface of a material that can cause sparks, shocks or cling. Learn how it is created by contact, pressure, heat or charge, and how to remove or prevent it with antistatic agents or methods.
Electrostatic induction is a redistribution of electric charge in an object caused by the influence of nearby charges. Learn how induction works, how to demonstrate it, and how to use it to charge or discharge objects.
Coulomb damping is a type of constant mechanical damping that absorbs energy via sliding friction. Learn about its history, modes, illustration, theory and examples of Coulomb damping in machinery and structures.
Electrical resistance is a measure of opposition to electric current, while conductance is a measure of ease of electric current. Learn how resistance and conductance depend on material, geometry, temperature, and other factors, and how they follow Ohm's law.
Learn about the history and types of electrostatic generators, devices that produce static electricity by friction, induction, or other methods. Find out how they are used for scientific experiments, medical applications, and other purposes.
