How many energy pathways are there?
4
What pathways transfers in an electrical circuit due to charges moving?
Electrical.
What pathway reacts when a force causes an object to move?
Mechanical force.
What happens in the radiation pathway?
Energy is given out from a source, such as light or sound.
What pathway is used when Energy is transferred from a hotter object to a cooler one?
Heating Pathway.
What unit of measurement is energy measured in?
Joules/ Kilojoules/ Millijoules.

True.
Can energy be created?
No. It can’t be destroyed either.
If someone is running and they get faster which energy store decreases and which energy
store increases?
Chemical energy decreases, Kinetic energy store increases.
The total energy before someone is running fast is 75J, What will it be after?
75J
