energy stores Flashcards
(6 cards)
the five energy stores
unit for energy
joules
1. chemical potential energy store
2. gravitational potential energy store
3. kinetic energy store
4. elastic potential energy store
5. internal (thermal) energy store
chemical potential energy store
energy stored in chemical bonds of substances that can be released through chemical reactions examples
fuels, food
gravitational potential energy store
energy stored in an object as a result of its position
GPE = mgh mass x gravitational field x height
elastic potential energy store
energy stored in an elastic object when it is stretched or compressed
examples elastic objects like rubber bands or bows
kinetic energy store
KE = 1/2 mv square
1/2 x mass (kg) x velocity (m/s) ^2
correct way of phrasing
the energy in the kinetic energy store transfers to other energy store through sound waves
