Velocity and Acceleration |Formula,Units and Graph derivation
Velocity is a rate of change in displacement with respect to time. As displacement is a vector quantity having both magnitude and direction, velocity is also a vector quantity. Acceleration is a rate of change in velocity with respect to time. An object undergoes acceleration whenever an object’s speed increases or decreases (usually referred to […]
Read MoreTypes of Magnet |Their Differences with Examples
Magnets are objects that produce a force that attracts other ferromagnetic materials, like iron. They also either attract or repel other magnets. These magnets are broadly classified into 3 types like Permanent magnet Induced magnet Electromagnet Ancient people learned about magnetism when they discovered lodestones (or magnetite) which are naturally magnetized pieces of iron ore. […]
Read MoreHow thermostat works |Their Types, Examples and Applications
What is a thermostat? A thermostat is an instrument which keeps the temperature of a system at a constant level. It is designed to sense the temperature of a particular system and then perform actions to make the temperature remain at a constant level. The word ‘thermostat’ comes from two ancient Greek words: thermo (which […]

12 Uses of Light in Our life| Its Importance and significance
Light is a valuable resource present. It is one of the most exciting things which has been surprising the scientists for long. Even famous scientists like Albert Einstein and Newton were fascinated by the light so much. Hence, Einstein proposed E=MC², and also studied the photon and wave nature of light to a large extent. […]
Read MoreLight Energy | Sources, Examples & Facts
Light energy is a type of kinetic energy. It was a fascinating thing for many scientists like Einstein, Faraday, and Maxwell etc. Light is the only non-materialistic thing which is visible to naked eyes. One can see, feel it as the heat but cannot hold it and contain it as such. It travels from one […]
