What is force???
Force is an external push or pull on an object that causes it to change speed, direction, or shape. But how is force created? Force is produced by the transfer of energy from one object to another. When a force is applied to an object, energy is transferred to that object, which results in a […] More

Energy and its different forms
Energy is the ability to do work or cause a change. Work is done when you apply energy to an object and move it a certain distance. There are different forms of energy: Potential – energy due to position or structure: Gravitational Electrical Chemical energy – potential energy in chemical bonds Kinetic – the energy […] More

What would happen if there was no capacitance?
Capacitance is a measure of an object’s ability to store energy in the form of charge and electric potential. If there were no capacitance, that would mean there is no such thing as an electric field or electromagnetic force. Now the electromagnetic force is one of the 4 fundamental forces that govern the universe. If […] More
