mechanical energy is made up of what two energy types
stored energy(potential) and energy of motion (kinetic)
what is an open circuit
one that does not turn on, and is incomplete. energy cant flow
What charges attract?
opposite/different charges
incomplete circuit
a full/connected circuit that allows energy to flow (turns on)
What is an opinion vs fact
fact is a true statement
feeling is an personal feeling towards something
what would be evidence of Light energy
lights turning on
what is a closed circuit?
a closed circuit is a complete circuit, that allows energy to flow
What does it mean to repel?
move away from!
conductor
materials that allow heat to flow easily
insulator vs conductor
insulators does not pass through
conductors allow electricity to pass through
what is the definition of energy
ability to do work or cause change
What does an insulator do?
prevents electrical Currents from passing through, (think the outside rubber of wires) insulators do not allow energy to flow.
How are magnetic forces and static forces similar?
(n n) and (s s) repel
(s n) attract
(+ +) and (- -) repel
(+ -) attract
What is the definition of a circuit?
circular/loop shape path along which charges can flow through
What is the difference between an observation and inference?
observation is using your senses( to look/ to touch/to smell/ to hear)
inference (statement based on observations)
think... is that a cat or does it just look similar to a cat so you think its a cat
what is an example of chemical energy
battery
When do you have evidence of a closed circuit?
when something turns on.. lights, motors, buzzers, machines, etc
What happened with the charge balloon and the salt? why
statements about future events based on information
prediction
Investigation vs experiment
experiment is an investigation in what all variables are controlled and tested
investigation is a procedure carried out to observe, study or test something to find out more information about it
what causes a high pitch?
high pitch- faster vibrations
low pitch- caused by slower vibrations
What does a switch do to a circuit?
What is a neutral object?
one that has no forces acting on it
what is a blueprint and what does it consist of... think of all
a detailed drawing. consists of labels, diagrams, arrows, descriptions, MEASUREMENTS
Kinetic energy vs potential
kinetic- energy of motion
potential- stored energy
