chemical energy

• potential energy that is released when links between particles are broken or created
• nuclear energy
• thermal energy
• a source of power that is released when links between particles are broken or created

nuclear energy

• is the same thing as chemical energy
• is stored in the food we eat
• potential energy that is released when the links between particles are destroyed
• stored energy that is released when the links between particles are broken

thermal energy

• is the internal energy of an object due to the energy of motion of its particles
• is the external energy of an object due to the energy of motion of its particles
• is the nuclear energy of an object due to the energy of motion of its particles
• is the chemical energy of an object due to the energy of motion of its particles

• batteries

the flow of electricity through a conductor

• insulator
• electric current
• conductor current
• thermal current

What is a conductor?

• a material through which electricity does not flow
• a material through which electricity is destroyed
• a material through which thermal energy is destroyed
• a material through which electricity flows easily

What is an insulator?

• a material that slows or stops the flow of energy
• a material that speeds up the flow of electricity
• a material that creates heat energy
• a material that destroys sound waves

A path through which electric current can flow is a...

• voltage source
• insulator
• resistor
• circuit
