the ability to do work
What is energy?
the energy that makes things warm.
What is thermal energy?
the energy of things that are moving.
What is mechanical energy?
a rotating turbine generates electricity to power a blow dryer
a pot sitting on a hot stove
What is conduction?
the movement of energy from one location to another.
What is energy transformation?
the energy that comes from electricity.
What is electrical energy?
the energy that travels through the air as sound waves.
What is sound energy?
a lion on a cliff's edge pounces onto a deer below and consumes it
What is gravitational --> mechanical --> chemical?
hot air inflates a hot air balloon
What is convection?
the idea that while energy can be transferred or transformed, the total amount of energy does not change.
What is the Law of Conservation?
the energy from magnets or magnetic fields.
What is magnetic energy?
the energy stored in food, fuel, or batteries that we can use later.
What is chemical energy?
What is electrical --> radiant --> thermal?
the sun causes water in a pond to evaporate
What is radiation?
when something gets bigger because it gains heat, s its particles heat up, and move faster and spread farther apart.
What is expansion?
the energy carried by light.
What is radiant energy?
the energy that is stored when something is stretched or squished.
What is elastic energy?
a battery powers a phone that chimes when turned on
What is chemical --> electrical --> sound?
an oven mit gets warmer when taking out a hot baking dish
when something gets smaller because it loses heat (particles cool down, they move slower and get closer together).
What is contraction?
the energy that occurs because of its height above the ground.
What is gravitational energy?
the energy that is stored inside tiny particles (atoms).
What is nuclear energy?
a person standing on the edge of a diving board pushes down to bend the board and bounces up
What is gravitational --> elastic --> mechanical?
a bowl of oatmeal cools
What is convection?
