What type of heat transfer occurs through direct contact? CONDUCTION What type of heat transfer occurs through circulating currents? CONVECTION What type of heat transfer does not require a medium? RADIATION What is the ability to do work? ENERGY This law states that energy can neither be created nor destroyed- only transformed. THE LAW OF CONSERVATION OF ENERGY What is the energy of an object due its motion? KINETIC ENERGY What is the energy of an object due to its position? POTENTIAL ENERGY What type of energy is due to the transfer of thermal energy? HEAT ENERGY What type of energy provides heat and light for the Earth? What devices are used to convert solar energy into electrical energy? What type of energy is stored within the particles of matter? What type of energy flows through an electric circuit SOLAR ENERGY SOLAR CELLS CHEMICAL ENERGY ELECTRICAL ENERGY What type of energy is due to both the position & motion of an object? MECHANICAL ENERGY What is the force of attraction or repulsion of magnetic materials? MAGNETISM What is the area surrounding a magnet that can attract or repel objects? MAGNETIC FIELD A coil of wire spinning around a magnet or vice versa can form this. ELECTRIC CURRENT An electromagnet that uses mechanical energy to produce electricity? GENERATOR An electromagnet that uses electricity to produce mechanical energy? ELECTRIC MOTOR The ability to apply a force to an object and move it a distance? WORK The SI (metric) units used to measure the force of an object? NEWTONS (N) The SI (metric) units used to measure the work done on an object? How is work done by an object or on an object calculated? What is the instrument used to measure force? What are devices that are used to reduce the amount of effort force? JOULES (J) WORK= FORCE x DISTANCE (W=FxD) SPRING SCALE SIMPLE MACHINES Which simple machine consists of a rigid bar placed over a fixed point (fulcrum)? What is a fixed point used to move a lever? Which simple machine consists of a grooved wheel and rope? Which simple machine consists of a sloping surface used to reduce the amount of effort force to lift an object? LEVER FULCRUM PULLEY INCLINED PLANE Which simple machine consists of 2 circular objects? What types of devices consists of more than one simple machine?
