Energy Transfer
What is energy transfer?
Energy transfer is the movement of energy from one location to another.
What is a conductor?
A conductor is a material that allows electricity or heat to flow through it easily.
What is a closed path for electricity?
A closed path for electricity is a complete circuit that allows current to flow.
Name a way that energy moves through water.
Energy can move through water in the form of waves.
Name an example of an insulator.
Rubber is an example of an insulator.
How can electrical energy produce light?
Electrical energy can produce light when it flows through a light bulb.
How do sound waves travel?
Sound waves travel through vibrations in the air, liquids, or solids.
What do conductors do with electricity?
Conductors allow electricity to flow through them.
Give an example of thermal energy from electricity.
A toaster converts electrical energy into thermal energy to toast bread.
Give an example of energy transfer from motion.
A moving car transfers energy to the air, causing it to move.
How do insulators affect heat transfer?
Insulators slow down or prevent heat transfer.
What happens if a circuit is broken?
If a circuit is broken, electricity cannot flow, and the device will not work.
Explain how energy transfer happens in a playground swing.
When someone pushes a swing, they transfer energy to the swing, causing it to move.
Compare conductors and insulators in terms of energy transfer.
Conductors allow energy transfer easily, while insulators resist energy transfer.
Describe how electrical energy travels in a circuit.
Electrical energy travels from the power source, through conductors, to various components and back to the source in a closed loop.
