energy stores and transfers Flashcards
How many stores of energy are there?
7
Kinetic energy
All moving things store kinetic energy, e.g. Running πββοΈ
Thermal energy
The energy a substance nor and object stores because of its temperature , e.g. π₯
Elastic potential energy
The energy stored in a springy object when you stretch or squash it, e.g. tennis ball πΎ
Gravitational potential energy
The energy stored in an object because of its position above the ground, e.g. plane βοΈ
Chemical energy
Energy stored in a fuel, e.g. battery π, food π², muscles πͺ
Magnetic energy
Magnets π§²
Electrostatic energy
