periodic table
what is a fossil fuel
a nonrenewable energy source formed from the fossilized remains of ancient plants and animals buried and transformed over millions of years by heat and pressure
A wave is a repeating disturbance that transfers energy through matter or space
What is a simple machine?
A simple machine is a machine that does work with only one movement of the machine.
in what ways can atoms differ from each other
variations in the number of protons, neutrons, and electrons they possess
what kind of energy does a power plant create
electrical energy
how are fossil fuels made?
fossil fuels are formed over millions of years from the remains of ancient plants and animals
What is a Medium
A medium is matter through which a wave travels
What is energy?
Energy is the ability to cause change.
what are atoms made of
protons, neutrons, and electrons
how can you get the energy you need with the least impact on the environment
prioritize renewable energy sources like solar, wind, and hydroelectric power
what are two nonrenewable resources
coal and oil
What are the high and low points of a wave called?
Crest and Troughs
What is Kinetic energy?
Kinetic energy is energy due to motion
what do atoms of different elements have in common with each other
composed of the same subatomic particles
how can the flow of electricity be compared to the flow of water
Electrical current, the flow of electrons, is analogous to the flow of water through a pipe
how are renewable resources used
to generate electricity, heat, and transportation fuel
What is the period of a wave for?
The period of a wave is the amount of time it takes one wavelength to pass a point.
What is system?
A system is anything around which you can imagine a boundary.
how are the elements in each group of the periodic table similar to each other
they have the same number of valence electrons in their outermost shell
what is the difference between charging by contact and charging by induction
Charging by contact involves direct physical touch between objects, leading to a transfer of charge. Charging by induction, on the other hand, occurs without physical contact, through the influence of an electric field from a nearby charged object
what is acid rain caused by
the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere
What is Amplitude?
Amplitude is a measure of the size of the disturbance from a wave.
How does Potential energy work
Potential energy is stored energy that is from the interactions between objects.
what are the three main categories of elements and regions of the periodic table
metals, nonmetals, and metalloids
what types of charges exert forces from each other
positive and negative charges
