3 energy that is stored is called ______________ energy\n4 ______________ energy is the sum of kinetic and potential energy.\n5 what is the biggest source of light energy?\n6 what is electrical energy? what is an example of electrical energy?\n7 a heater is an example of ______________ energy.\n8 write true if the statement is true and right false if the statement is false the slower the molecules move, the higher the thermal energy\n9 when objects vibrate, ______________ energy is created\n10 can electrical energy change to sound energy? explain your answer
Answer
Brief Explanations:
- Potential energy is stored energy.
- Mechanical energy is the sum of kinetic and potential energy.
- The Sun is the biggest source of light energy.
- Electrical energy is the energy due to the movement of electric charges. An example is the energy used to power a light - bulb.
- A heater converts electrical energy into thermal energy.
- The slower the molecules move, the lower the thermal energy, so the answer is false.
- When objects vibrate, sound energy is created.
- Yes, electrical energy can change to sound energy. For example, in a speaker, electrical signals are converted into sound waves.
