Definitions
This word means that energy has been spread out and cannot be recovered.
What is dissipated?
It is this situation of energy change: “John dropped a ball.”
What is gravitational potential energy to kinetic?
Energy stored due to movement of object.
What is kinetic energy?
The movement of energy from one location to another.
What is energy transfer?
The units for measuring energy
What is joules?
A quantity that must be changed or transferred to make something happen.
What is energy?
It is this situation of this energy change: “Jayden ate food and then ran for 10 minutes.”
What is chemical energy to kinetic energy?
Heat energy sorted in hot objects and transferred to colder objects.
What is thermal energy?
The principle that energy cannot be created or destroyed, only changed from one form to another.
What is the Law of Conservation of Energy?
Energy released from atomic nuclei.
What is nuclear energy?
The energy stored in an object due to its position above the gravitational field.
What is gravitational potential?
It is this situation of energy change: “The TV turned on and played a video of vaporising chicken in acid. Next the sound of bubbling can be heard from the TV.”
What is electrical energy to sound energy?
Energy stored when things are stretched or squeezed to change their shape.
What is elastic potential energy?
Energy from the Earth’s interior.
What is geothermal energy?
It is this situation of energy change: “Bob has just ate at a 5-Star Michelin Star Restaurant. Then, he walks to the train station.”
What is chemical energy to kinetic energy?
To keep or accumulate for future use
What is stored?
It is this situation of energy change: “You use wood to heat up a pot of water. The fire rages as you take out the pot of boiling water.”
What is chemical energy to thermal energy to light energy?
Visible energy from luminous objects.
What is light energy?
Reactions that release energy, where products have less energy than reactants.
What are exothermic reactions?
KE = 1/2 * mv²
What is the formula for kinetic energy?
The combination of altering, modifying and transforming energy.
What is energy change?
It is this situation of energy change: “In a power station, natural gas is burned. Then, it powers a large generator to spin around. Lastly, it generates electricity to be used in homes and buildings.”
What is chemical energy to thermal energy to kinetic energy to electrical energy?
Stored in the bonds of atoms and molecules.
What is chemical potential energy?
Reactions that absorb energy, where products have more energy than reactants.
What are endothermic reactions?
Transformations from one form of energy to another or to changes in the total energy in a system.
What are changes of energy?
