Energy Transfer and Energy Transformation - Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The rad..

Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The radiant energy of sunlight cannot be utilised directly by all..

The storage and expenditure of energy in an ecosystem is in accordance with the laws of thermodynamics (basic laws of thermodynamics). The first law of thermodynamics is the law of conservation of energy, which says that 'energy can neither be created nor destroyed b..

The figure shows a vibrating simple pendulum, O is the point of suspension. When the centre of gravity of the bob is vertically below the point of suspension, the position of the pendulum is called the rest position or mean position. Let us say that the bob is displaced to a position E 1 . When ..

For a given power requirement, one has the choice of the relative values of I r m s and E r m s . That is, for the product to be a constant, we can choose a relatively large current I and a relatively small potential difference v or just the reverse. In an electric power distribution system, it is ..

Energy Flow - Energy is the capacity to do work. Solar energy is transformed into chemical energy by the process of photosynthesis, and is stored in plant tissue and then transformed into mechanical and heat forms during metabolic activiti..

Every organism has a tendency to increase its entropy, which is very much in accordance with the second law of thermodynamics. In order to maintain its organisation at the molecular, cellular and organismic levels, every organism is forced to obtain energy from its surroundings, so that ..

Thus, the total energy is a constant. At the equilibrium position, y = 0 At the extreme position, y = A, As the body oscillates, there is a transformation between kinetic energy and potential energy, maintaining the total energy const..

Law of conservation of energy states that the energy can neither be created nor destroyed but can be transformed from one form to anothe..
