The Origin of Magnetism Explain the origin of magnetism Chinese were the first to use the metal magnetite called lodestone. A Lodestone was capable of attracting small iron pieces and it was used as a crude navigation compass by Greeks. Lodestones…

Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a…

Explain the concept of static electricity Static electricity refers to the electric charges stored on a conductor. The Origin of Charges Explain the origin of charges When a plastic pen is rubbed with a cloth, it acquires the property of…

The Concept of Pressure Explain the concept of pressure Pressure is defined as the force per unit area. OR Pressure is the force acting normally (perpendicularly) per unit surface area. It is calculated by the formula: Pressure = Force (f)/Area…

State of matter is defined in terms of the phase transitions which indicate the change in structure and properties. Solids, liquids and gases all are made up of microscopic particles. The behavior of all these particles also varies in three…

Archimedes’ principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. The Concept of Upthrust Explain…

A force is an interaction that causes a change. In mechanics, a force is an interaction that causes a change in velocity (an interaction that causes acceleration).

The Concepts of Measurement Explain the concepts of measurement Measurement is the process of assigning numbers to observations or events. Importance of Measurement in Real Life State the importance of measurement in real life Measurements are so often taken for granted,…

Rules in a Physics Laboratory State rules in physics laboratory While working in the lab, individuals are advised to adhere to specific lab rules to ensure their safety, that of other people working in the lab and the safety of…
