P1 Energy stores and potential stores Flashcards
What are the 8 energy stores?
Thermal
kinetic
gravitational potential
elastic potential
nuclear
electrostatic
magnetic
chemical
What is the conservation of energy?
Energy cannot be destroyed or created, but transferred to another store.
what is Earth’s gravitational field strength?
10N
How can efficiency be improved?
insulating objects, making them ore streamlined or lubricating them.
Where does all energy get transferred to?
Thermal Energy
what is specific heat capacity?
the amount of energy needed to raise the temperature of 1 kg by 1’c
What is internal energy?
total energy stored by particles in a substance. It is made of both kinetic energy and potential energy
What is work done?
work done is an energy transfer, work can be done when current flows(work is done against a resistance in a current) or by a force moving an object.
