energy - It is the ability to cause motion and other changes in matter. , temperature - The measurement of the average kinetic energy of particles in an object. , thermometer - It is used to measure temperature. , conduction - The transfer of heat energy from one object directly into another. , thermal Insulator - A material that does not conduct heat. , convection - It is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids, light - A form of energy that can be seen when it interacts with matters. , reflection - It is the bending of light waves as they pass from one material to another. , sound - These are longitudinal waves produced by vibrating bodies. , pitch - It is the highness and lowness of sound. , heat - It is the energy that flows between two objects because of a difference in temperature. , electricity - It is a form of energy that powers most devices which move or operate in response to the electricity flowing through them. , circuit - It is the path through which a current flows. , series - A circuit in which the current must pass through all the electrical devices. , parallel - A circuit in which the electric current passes through two or more branches or connected parts at the same time before it combines again., electromagnet - An electric circuit that produces a magnetic field., ampere - The unit used to measure the amount  of an electrical current., magnetic field - The region around the magnet where its influence is felt. , resistor - A part of circuit that resists the flow of energy used to produce light. , magnetism  - It is the force exerted by magnet s when they attract or repel each other.,
