Physics

General purpose of this lecture is to present on Speed and Acceleration. It is a tutorial study based lecture. Acceleration is the rate at which velocity…

The measure of energy given to the charge flowing in a circuit. The greater the voltage, the greater the force or “pressure” that drives the charge…

Friction is the force that two surfaces exert on each other when they rub against each other. Some Causes of Friction are: the strength of the…

Friction is a Force that always pushes against an object when it touches another object. When two things are in contact with each other, there will…

A force is an influence on a system or object which, acting alone, will cause the motion of the system or object to change. If…

Electric Current is a closed path through which electrons can flow. Electrons flow because of a difference in potential. When a switch is turned on it causes…

Primary objective of this lecture is to present on Central Concept of Closed Circuit. Closed circuit is an electric circuit through which current can flow in an…

This lecture focus to describe on How to Work Electrical Circuits? A simple electrical circuit contains four parts: a power source, a load, connectors and a switch. An…

This lecture introduce on Electricity Friction. An object becomes charged by: Friction; Conduction and Induction. Voltage is a measure of the potential difference between two places in a circuit. The unit…

Principle objective of this lecture is to present on Electricity Practical. It is tutorial study based presentation. here briefly describe on Charges; Electrons; Voltage; Current; Series; Parallel and Resistance. There are kinds of electrical…

Major objective of this lecture is to present on What is a Motor? Motor is a device that changes electrical energy to mechanical energy that can do…

The aim of this lecture is to present on What is a Generator? Generator is a machine that changes mechanical energy to electrical energy. Usually use moving magnets…
