a black hole is a cosmic or celestial body of very strong gravity, from which no matter even electromagnetic radiation can escape and it emits no light.Read More

## The Gyroscope and its applications

The gyroscope the name is derived from two Greek words "gyros" means "turn" or revolution and "skopein" means "view.". The above derivatives say the meaning of a gyroscope is "to view the turning".Encyclopaedia Britannica defines the "gyroscope - device containing a rapidly spinning wheel or circulating beam of light that is used to detect the deviation of an object from its derived orientation" Offline Dictionary of English says gyroscope that-"an apparatus composed of a wheel which spins inside of a frame (gimbal) and causes the balancing of the frame in any direction or position" Now we may conclude that the gyroscope is a device based on precession motion. It has a rotor a freely spinning disk with an axle installed on the gimbal(which is fixed to a massive strong frame structure), and can navigate in three directions of the space, to maintain the orientation, irrespective of any directional movement of the base.Read More

## What do you know about power? A fact analysis.

In simple we may say -rate of doing work in unit time is power. Further we may say-the amount of energy converted or transferred per unit time is called power. The SI unit of power is watt(w), which is Joules per second (J/S). SI base units-kg.m2.s-3Read More

## How many forms have energy? Know more.

In simple term we may say, capacity of doing work is called energy. Total energy of a body is equal to the capacity of the work done by body. The basic unit of energy is joule(J) of metric system or International system of units (SI). In SI unit calculation made as such- mass in the unit of kilogram, distance in meters, time per second squared.Read More
