Electricity & Circuits
The presence and/or flow of electric charges
What is electricity?
A disturbance that carries energy from one location to another location
What is a wave?
Made up of tiny particles, such as atoms, molecules, or ions
What is matter?
The ability to do work
What is energy?
A measure of gravitational force on an object (changes with location)
What is weight?
The flow of charged particles
What is an electric current?
A substance or material that carries a wave
What is a medium?
Energy of motion
What is kinetic energy?
Joules (J)
What is the SI unit for energy?
Newtons (N)
What is the SI unit for weight?
These control the movement of electric current by providing paths for electrons to follow
What is a circuit?
Top of a wave/Bottom of a wave
What is a crest and trough?
Least amount of kinetic energy
What is a solid?
Stored energy due to an object’s position--energy ready to go
What is potential energy?
Amount of matter in an object (does not change with
gravity)
What is mass?
The path of this is a closed loop
What does an electric current look like?
( ) is how much energy the wave carries. It is the distance from rest to crest or rest to trough.
What is amplitude?
Has a definite shape and definite volume
What is a solid?
The energy stored in elastic materials as the result of
their stretching or compressing
What is elastic potential energy?
Kilograms (kg)
What is the SI unit for mass?
The potential difference between two points in a circuit
What is a voltage?
The distance from crest to crest or from trough to trough
What is a wavelength?
A state of matter that starts out as a gas and becomes ionized
What is plasma?
Potential energy that is related to an object's
height above the ground
What is gravitational potential energy?
The rate at which velocity changes or the rate in which you speed up, slow down, or change directions
What is acceleration?
