Electric current is different from static electricity and it involves the flow of electric charge. The flow of electrons in solid conductors, and the flow of ions and...
Static electricity refers to an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current...
A simple magnet is a magnetised bar of iron. It attracts and holds iron pieces but does not attract pieces of copper. Those materials attracted by a magnet...
Sound waves come from vibration of material objects. For example, vibrations of vocal cards in the larynx, and the vibrating strings of the sitar produce sounds. The frequency...
Fluids refers to the substances which can flow when an external force is applies to them. Both liquids and gases come under the category of fluids. Fluids don’t...
Elasticity refers to that property of an object by virtue of which it regains its original configuration after removal a deforming force. Deforming force is the force which...
This article discusses important concepts related to Inertia, Force, Newton’s Laws of Motions, Law of Conservation of Linear Momentum, weight and friction concepts for General Knowledge of Physics...
When an object moves in circular path, it is called circular motion. If the speed of the object in circular motion remains constant, then it is called uniform...
Under gravity, acceleration is 9.8 m/s² and is denoted by g. When an object is falling freely under gravity, then the above equations would be adjusted as follows:...
