4th quarter

• Energy - It is the capacity to do work
• Kinetic energy - energy of an object due to its motion, measured in joules (J)
• Potential energy - energy stored in an object due to its position or shape.
• Heat - is a form of energy that is moving between two bodies with temperature difference
• Thermal Energy - The total amount of heat possessed by all particles within a system
• Conduction - heat is transferred by direct contact
• Convection - The transfer of heat by the movement of hot and cold air or fluids
• Radiation - the transfer of energy in the form of electromagnetic waves, such as light
• Temperature - is the degree of how hot or how cold a body is
• Projectile motion/ freefall - is motion in two directions
• trajectory - the path that the projectile travels
• momentum - their force or speed of movement
• Powerplants - are industrial facilities that use different sources of energy and convert them into electrical energy
• Thermal power station - is a facility that capitalizes on the flow of thermal energy or heat as the source of energy
• Generator - A device that converts mechanical energy into electric energy, or vice versa.
• Green energy - an energy source that is renewable and has little negative impact on the environment
• Dry stem geothermal power plant - the water is superheated by earth is turned into dry steam in its depths
• Dry steam - saturated steam
• Flash steam geothermal power plant - pumps up the heated water into the flash tank
• Binary steam geothermal power plant - the heated water or steam from beneath the crust or near a magma dome surges into a heat exchanger
• Heat pumps -are the reverse of heat engines because they work to direct the flow of heat
• powerhouse - is an individual facility that is under the same power plant
• Biofuel - refers to fuel from powerplant matter that is grown and processed
• Nuclear power - the fission or splitting of heavy radioactive atoms releases large amounts of energy with less massive radioactive atoms as a by-product
• Solar power - the radiation from the sun is harvested by photovoltaic cells
• Work done - a net force that can make a body change its displacement parallel to the force applied
• electric meter - measures the amount of electric power the facility uses in a certain amount of time
• fuse box - is a box that houses the fuse
• ground/earth - these are conducting paths for the excess charges to leak off into the earth or the ground
• impulse - is the product of the force of impact and the time tht force is being applied
