Energy Types
What type of energy is produced when running 5km?
Kinetic energy
What force keeps us on the ground and prevents us from floating into space?
Gravity
Which Australian state or territory is home to Uluru?
Northern Territory
What is the difference between input and output energy?
Input energy is the energy supplied to a system, while output energy is the energy produced by the system.
What type of energy is produced when pulling an arrow back in a bow (not letting go)
Elastic Potential Energy
What is the largest planet in our solar system?
Jupiter
What is the only continent with no permanent human population?
Antarctica
Define the Law of Conservation of Mass
That energy is neither destroyed nor created. It is transformed.
Name the type of energy in a battery.
Chemical potential energy
What is the name of the process where plants convert sunlight into chemical energy?
Photosynthesis
What is the smallest country in the world by land area?
Identify the input energy and useful output energy when a toaster is used to cook bread.
Input: Electrical
Useful Output: Thermal/Heat
Explain how the height and mass of an object affect its gravitational potential energy.
As height and mass increases, so does the GPE.
What is the name of the layer of the Earth that is made mostly of liquid iron and nickel?
What is the name of the imaginary line that divides Earth into the Northern and Southern Hemispheres?
The Equator
Draw an energy flow diagram showing the energy transformations that occur when a battery-powered torch is switched on.
Chemical potential energy (battery) → Electrical energy → Light energy
What type of energy is associated with the movement of photons?
Light energy
What is the term used to describe an organism that can produce its own food using light or chemical energy?
Autotroph
Which ocean is the deepest in the world?
Pacific Ocean
Explain why a car engine produces wasted energy. Identify two forms of wasted energy produced by the engine.
A car engine transforms chemical energy from fuel into useful kinetic energy to move the car. However, some energy is transformed into unwanted thermal (heat) energy and sound energy.
