Energy Stores Flashcards
What is kinetic stored in?
moving objects
What is gravitational potential stored in?
Objects raised above ground
What is elastic potential stored in?
stretched or compressed objects
What is thermal stored in?
All objects due to particle movement
What is chemical stored in?
Substances that can release energy in a chemical reaction
What is the nuclear stored in?
The nucleus of atoms
What is magnetic stored in?
Magnets attracting or repelling
What is electrostatic stored in?
separation of charges
What are the two things the amount of energy in an objects gravitational potential store depends on?
- How heavy the object is
- how high above the ground it is+ force of gravity
Describe charging by friction.
Static charge built up from two insulating materials rubbing against one another.
What is potential difference?
Separation of charges.
What happens if the potential difference is high enough?
Charges move= spark
Why are electrons lost easily?
Because they are outside the nucleus and have a weakly bound
