Energy is the ability to do work. there are six types of energy.
If the body is at rest, it will remain at rest,if it is in motion it will continue in motion with constant speed in a straight line unless there is a net force acting upon it.
Batteries store electricity for appliances that you can not or do not want to plug in.
The electric circuit is completed through a battery and push switch button connected to the terminal T1 and T2.
Thomas Alva Edison invented the electricity. He invented electric bulb,lamb,etc.The electric light system was more than just the incandescent lamp, or "light bulb."
Electricity, all the phenomena that result from the interaction of electrical charges. Electric and magnetic effects are caused by the relative positions and movements of charged particles of matter.
The presentation deals with Band Theory of solids, Intrinsic & extrinsic semiconductors, Junction Diod, Transistors-its properties & uses, Radio & T.V.- their basic principle of working, Computer- basic principles of working.
Energy has many interchangeable forms viz.Heat, Light, Mechanical power, electricity.
It is defined as an agent which produces or tends to produce, destroy or tends to destroy motion.
It is a combastable substance having carbon as the major constituent which is the proper burning profiles a large quantity of heat. That can be used economically for domestic and industrial purposes.
Example-coal, wood, .P.G gas
Heat is a form of energy. When you rub your hands together heat is produced. As long as we rub the objects heat is continuously produced because of Friction.
Energy appears in nature in two forms, disordered and ordered. The disordered form, of which heat is a prime example, can be converted into other forms, such as mechanical energy, through a heat engine.
According to law of flotation,the weight of the floating is equal to the weight of the liquid displaced by it.The center of gravity of the floating body and the center of gravity of the liquid displaced are in the same vertical line.
The basic scientific principle behind a laser was first put forward by DR. charles H.townes in 1954. The efforts of several scientists laser led to the development of the first laser called pulsed laser in 1960.
The presentation displays law of reflection.
A Lens is a piece of transparent material bound by curved surface.There are two types of lens: concave & convex.
Reflection and Refraction are two important Phenomena of Light.Concave Mirror and convex mirror are called spherical mirror.
Light is a form of energy.Without light we can’t live in this world.We have the natural source of light,this sun.
We are seeing light -- light that somehow left objects far or near and reached our eyes. Light is all our eyes can really see.
Light is a form of electromagnetic radiation that causes the sensation of sight.
The metal which attracts certain other metals and shows the direction like magnetite is called as Magnet. This quality of a metal is known as magnetism.
If the forces acting on the body in the displaced position tend to restore it to its original position, the equilibrium is said to be stable.
When the position of a body continuously changes with respect to time and its surroundings, the body is said to be in motion.
Machine for converting energy into motion or mechanical work. The energy is usually supplied in the form of a chemical fuel, such as oil or petrol (gasoline), steam, or electricity.
Any arrangement which makes use of a combination of lenses,mirrors or prisms,is called an optical instrument. All the optical instruments are based on the laws of reflection and refraction.
The overwhelming majority of car engines still employ the four-stroke cycle (four piston strokes per cycle), invented by Nicholas Otto in 1876.
The working of an internal combustion engine is divided into four stages called four strokes of the engine and hence the engine is called a four stroke engine.
Petrol Engine was introduced by the German engineers Gottlieb Daimler and Karl Benz in 1885. It is considered as one of biggest achievement in the automotive field.
CHARGING STROKE Piston moves outwards and suck gas In trough valve A.
Eye, light-sensitive organ of vision in animals. The eyes of various species vary from simple structures that are capable only of differentiating between light and dark.
Coordinator initiated the interactive mode of this topic by teachers & students to understand the concept of reflection (normal flight of light).
Refraction happens because the light slows down in the material.
The direction of our sight in a specific direction is sometimes referred to as the line of sight.
The first law of refraction states that incident ray, the normal drawn on the surface of refraction & refracted ray lie in one plane.
Refraction is the bending of light that takes place at a boundary between two materials having different indices of refraction. It is due to a change in the speed of light as it passes from one medium to another
Robert Hutchings Goddard Robert Goddard was an aerospace pioneer who designed the liquid-propellant rocket and made one of the first serious proposals for flight to the moon.
Let's learn the logic of how a rocket engine works. In fact the logic behind is very simple.
This is a pictographical representation of how rocket works.
Centrum Sound is a principal provider of Assistive Listening Devices for personal applications. In addition, we carry a full range of Professional Sound Reinforcement Equipment.
If you speak one word at the microphone at a level of 80 dB and the loudspeaker returns that word to the microphone at 80 dB, then you can go home.
Energy is the ability to do work. There are two types of energy: potential & kinetic energy.
The evolution of species on the land is linked to and driven by various climatological and geological changes that operated on the land surface of the earth.
X-rays are electromagnetic waves like radio and light waves. These all travel at the speed of light, which is 300,000km per second.
