Energy

 1.Energy

Energy is the ability to do something or to move something. Energy is everywhere in us,around us,in nature,light,wind and in our daily lives.

Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed; matter and energy may also be converted to one another. The unit ofmeasurement for energy in the International System of Units (SI) is the joule (J).

Types of Energy 

*light /solar energy 

*Heat energy

*moving energy

 

The energy  we use to power everything  from our homes to schools  and workplaces comes from a variety  of different  sources. These can be broken down into renewable energy sources. A renewable energy source is any natural resources  that  can replace  itself  quickly  and dependably. Below are some of the sources of energy:

*Wind energy (renewable air movement)

*Solar energy (renewable  sun radiation)

*Hydropower(Renewable water flow)

*Natural  gas(non-renewable fossil  fuel)

 What is an Ecosystem? An ecosystem is a structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interactions between organisms and their environment. The term “Ecosystem” was first coined by A.G.Tansley, an English botanist, in 1935. Read on to explore the structure, components, types and functions of the ecosystem in the notes provided below. Structure of the Ecosystem The structure of an ecosystem is characterised by the organisation of both biotic and abiotic components. This includes the distribution of energy in our environment. It also includes the climatic conditions prevailing in that particular environment.  The structure of an ecosystem can be split into two main components, namely:  Biotic Components Abiotic Components The biotic and abiotic components are interrelated in an ecosystem. It is an open system where the energy and components can flow t...

 Magnetism is the force that pulls (attracts) or pushes (repels) an object which contains metal towards, or away from, a magnet. A magnet has an area around it over which it can exert a force on objects. The further away the object is from the magnet, the weaker the force. Properties of Magnets are: We already know that magnets are made up of the magnetic substance. Magnets have certain important properties. They are: Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a direction.  Forces and fields between  magnets are: The magnetic force is the force of attraction or repulsion that arises between electrically charged particles due to their motion  The magnetic force between two moving charges may be described as the force exerted upon their charge by t...
