It is this situation of energy change: “John dropped a ball.”

What is gravitational potential energy to kinetic?

100

Energy stored due to movement of object.

What is kinetic energy?

100

The movement of energy from one location to another.

What is energy transfer?

100

The units for measuring energy

What is joules?

200

A quantity that must be changed or transferred to make something happen.

What is energy?

200

It is this situation of this energy change: “Jayden ate food and then ran for 10 minutes.”

What is chemical energy to kinetic energy?

200

Heat energy sorted in hot objects and transferred to colder objects.

What is thermal energy?

200

The principle that energy cannot be created or destroyed, only changed from one form to another.

What is the Law of Conservation of Energy?

200

Energy released from atomic nuclei.

What is nuclear energy?

300

The energy stored in an object due to its position above the gravitational field.

 What is gravitational potential?

300

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?

300

Energy stored when things are stretched or squeezed to change their shape.

What is elastic potential energy?

300

Energy from the Earth’s interior.

What is geothermal energy?

300

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?

400

To keep or accumulate for future use

What is stored?

400

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?

400

Visible energy from luminous objects.

What is light energy?

400

Reactions that release energy, where products have less energy than reactants.

What are exothermic reactions?

400

KE = 1/2 * mv²

What is the formula for kinetic energy?

500

The combination of altering, modifying and transforming energy.

What is energy change?

500

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?

500

 Stored in the bonds of atoms and molecules.

What is chemical potential energy?

500

Reactions that absorb energy, where products have more energy than reactants.

What are endothermic reactions?

500

Transformations from one form of energy to another or to changes in the total energy in a system.

What are changes of energy?
