If you charge an object via conduction, what is it that you must do?
Touch the materials together
400
This word describes a reaction that absorbs heat from the surroundings, usually making it feel cold
Endothermic (Endo is inside, so heat goes into it)
400
covalent bonds typically form between ___________ & _____________
nonmetals & nonmetals

The maximum potential energy someone on a playground swing experiences is where?
at the top of the swing arc!
Height & gravity & mass are the things that matter for gravitational potential energy.
Mass and gravity are unchanged here = only height is changing
400
Which of these is a resistor?
-Battery
-lightbulb
-wires
-iron core
Lightbulb! Any device that absorbs power from the circuit is a resistor, with some of them having a purpose of adding electrical resistance to slow current in a circuit, like the one in the image
500
which is more dense?
water
OR
water after you add salt
why?
.
water after you add salt, because there is more matter in the same sized amount of water, thanks to dissolved salt
