Types of Energy
What type of energy from the Sun helps plants grow and warms Earth's surface?
light energy (solar energy)
heat transfer
electric current/ flow
What do we call a complete, unbroken path through which electricity can flow?
closed circuit .
What form of energy does a battery store before it powers a toy?
What is chemical energy?
What is sound energy?
When a metal spoon sits in hot soup, heat travels through the spoon. What type of heat transfer is this?
What is conduction?
.
What kind of particles move through metal wires to carry electric current?
What are electrons?
What is a circuit called when a gap prevents electricity from flowing?
What is an open circuit?
When a battery lights a bulb, what form of energy travels through the wires to the bulb?
What is electrical energy?
What type of energy does a moving bicycle have?
What is kinetic energy?
How does heat from the Sun travel through the empty space between the Sun and Earth?
What is radiation?
What device provides the energy that pushes electric charges around a simple battery-powered circuit?
What is a battery?
What component can be used to turn a light bulb on and off by opening or closing a circuit?
What is a switch?
A toaster changes electrical energy into heat. What is the useful energy output?
What is thermal energy?
A stretched rubber band is ready to snap back. What kind of energy is stored in it?
What is elastic potential energy?
Warm air rises and cool air sinks, creating a circulating movement that transfers heat. What is this called?
convection
What happens to the current in a simple circuit if the circuit is broken and no longer forms a complete path?
What is the current stopping?
In a series circuit with two bulbs, one bulb is removed and the path breaks. What happens to the other bulb?
What is that it goes out because the circuit is broken?
A television uses electricity and produces light and sound. What happens to the electrical energy?
What is that it is transformed into other forms, including light and sound energy, and some thermal energy?
A flashlight uses batteries to produce light. Name two forms of energy involved in this change.
What are chemical energy and light energy? Electrical energy also occurs between them.
A student rubs their hands together and they become warm. Explain how motion energy changes into thermal energy.
What is friction converting some kinetic energy into thermal energy?
Why does a light bulb stop shining when a wire is disconnected from its battery-powered circuit?
What is the interruption of the complete path, which stops current from flowing?
Two bulbs are connected in parallel. One bulb burns out, but the other branch remains complete. What happens to the other bulb, and why?
What is that it stays lit because its branch still provides a complete path?
Trace the energy changes in a battery-powered toy car as it moves and makes noise.
What is chemical energy in the battery changing to electrical energy, then to kinetic energy, sound energy, and thermal energy?
