Work, Power and Energy

Work, Power, and Energy Learning Outcome Relation between work and energy. Relation among work, force, and displacement. Kinetic and potential energy. Transformation of energy in its source. Contribution of the sources of energy regarding economic, social, and environmental influence. Relation between transformation of energy and conservation of energy. Transformation of energy and how its uses hamper the balance of environment. Effective use of energy in developing activities. Effective and safe use of energy. Mass energy relation. Explain the power. Measure the efficiency. 4.1 Work What is work? If because of force-displacement happens then the product of force and component of displacement at the direction of force due to force is work. Work is the product of applied force on a body and its displacement along the direction of force. Unit of work: J (Joule) Dimension of work, [W] = ML2T-2 What is Joule? If due to the appliance of one newton force at the direction of force the applica

Physical Quantities and Their Measurements

Physical Quantities and Their Measurements Learning Outcome The scope and gradual development of physics. The objectives of physics. The physical quantities as the origin of physics.  The measurement and necessity of units. The difference between fundamental and derived quantities. Physics The branch of science which deals with matter and energy is called physics. The main objectives of physics are to establish the relation between matter and energy and to express it quantitatively on the basis of observation, experimentation, and analysis. Scope of Physics Physics is the key to all science. It is the fundamental branch of science because the foundation of other subjects is based on the principles of physics. For example, the principle of conservation of energy is a basic principle of physics used to explain the wide range of science starting from the structure of atoms to weather forecasting. Starting from Engineering to Medical Science, Astronomy to Oceanology, Biology to Psychology
