Energy types
Name a type of kinetic energy
Heat (thermal), light, sound, mechanical, magnetic (etc...)
I am standing still on the edge of a diving board, then jump off - transfer or transformation?
Transformation (potential to kinetic)
Transformation occurring when I boil the kettle (A -> B)
Electrical to heat
What is the dependent variable in an experiment?
The one we measure
Name a type of potential energy
I run full speed at my mate and knock him flying - transfer or transformation
Transfer (kinetic to kinetic)
Transformation when I roll a ball down the hill (A -> B)
Gravitational potential to kinetic
What are the controlled variables in an experiment?
True or False - Energy stored in a battery is a form of potential energy
True
I light the fireplace to warm up the room - transfer or transformation
Transformation (chemical to heat and light)
My arm is drawn back ready to release an arrow from a bow, and I let go (A -> B)
Elastic potential to kinetic
What is the independent variable in an experiment?
The variable we change / test
Give an example of where kinetic energy is being used in the classroom right now
Teacher's call.
My muscles use energy to lift the weights in the gym - transfer or transformation
Transformation (chemical to mechanical)
My mobile phone is used to play music out loud (A -> B
Chemical potential to sound
What is an inference?
Something we predict based on the knowledge we have
Give an example of where potential energy is being used in the classroom right now.
Teacher's call.
The sun's energy powers my solar hot water for my shower - transfer or transformation
Transformation (solar to chemical to heat)
I switch on my phone charger to charge up my battery (A -> B)
Electrical to chemical potential
Give an example of a generalisation
