Circuits
What is Electricity?
Electricity is the flow of electrons around the circuit.
What is a wave?
a disturbance that carries energy from one location to another location.
Matter is made up of...?
tiny particles, such as atoms, molecules, or ions.
Living organisms need...
energy for growth and movement.
what is weight
a measure of gravitational force on an object
What are circuits?
They control the movement of electric current by providing paths for electrons to follow.
Types of waves?
Transverse waves and Longitudinal waves
kinetic energy is
is the energy of motion.
All energy can be in either...
potential energy or kinetic energy.
Mass?
amount of matter in an object
What are the 3 main parts of a Circuits.
They need an energy source, a wire and a load for simple circuits to work
Substance that carries a wave? what is it made up of?
A medium. is a solid, liquid, or gas.
Increased temperature means
greater average kinetic energy, so most substances expand when heated.
Potential energy is stored in ....
energy due to an object’s position--energy ready to go.
Acceleration?
rate at which velocity changes or the rate in which you speed up, slow down, or change directions.
A path of a electric current?
Is a closed loop.
What are transverse waves?
Crest- top of wave
Trough- bottom of wave
States of matter?
solid, liquid, and gas.
Elastic potential energy is the..
energy stored in elastic materials as the result of their stretching or compressing.
Gravity
the force of attraction between all objects in the universe.
electric circuit allows electrons to do?
flow from a negative pole (excess electrons) to a positive pole (deficient in electrons).
What is amplitude and wavelength?
Amplitude- is how much energy the wave carries. It is the distance from rest to crest or rest to trough.
Wavelength- length of a full cycle of a wave from one point to the next at the same point. It’s the distance from crest to crest or from trough to trough.
what is the fourth state of matter?
Plasma
Potential energy that is related to
an object's height above the ground is known as gravitational potential energy.
Velocity
the speed of an object in a particular direction.
