General Flashcards
Define energy
The ability to do work
Define electrical energy
Energy that’s stored in charged particles within an electric field
Define electrical fields
Areas surrounding a charged particle that can exert force on other charged particles within the field, causing them to move and hence do work
Define energy transfer
When an object passes energy to another object
Give an example of energy transfer

What is an isotope
An atom that does not weigh the exact same on the periodic table
