modeling our orderly world
chemical reactions
energy
dynamics
kinematics
100
the systematic study of the universe.
what is science?
100
a process that changes a substance into one or more different substances.
what is a chemical reaction?
100
the difference between kinetic and potential energy.
what is the use or the possible use of energy?
100
every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
what is newtons first law?
100
the study of how things move.
what is kinematics?
200
observation, posing questions, research, and forming hypotheses.
what is the first four steps of the scientific inquiry?
200
hydrogen and oxygen combine to make.
what is H2O/water?
200
burning fossil fuel
Heat energy is transferred into kinetic energy
Kinetic energy is transferred to steam to turn the blades of the turbines
The turbine turns the shaft and makes electric energy from a generator
what is the stages of a power plant?
200
F = ma, or net force is equal to mass times acceleration.
what is newtons 2nd law?
200
the distance that is traveled in an amount of time.
what is speed?
300
investigation, analysis, conclusion, and communication.
what is the second half of the scientific inquiry?
300
**DAILY DOUBLE**
this is an example of what.
what is an exothermic reaction?
300
the substance that they burn in power plants.
what is coal?
300
for every action (force) in nature, there is an equal and opposite reaction.
what is newtons third law?
300
Energy equals mass times the speed of light squared.
what is e=mc2?
400
everything has what.
what is order?
400
the model that shows how many valance electrons an element has.
what is electron dot notation?
400
the part that mostly helps creates the energy.
what is the turbine?
400
9.81 m/s2.
what is acceleration to earth due to gravity?
400
1. Write down what you know
2. write the formula and solve the unknown
3. Plug in known values and evaluate
what is the formula for calculating speed?
500
a good model has this.
what is workability?
500
bubbles, color change, and odor all have one thing in common.
what is evidence of chemical changes?
500
the exchanger of the turbine/shaft rotation.
what is the generator?
500
a contact force that works against the motion of objects.
what is friction?
500
s=d/t.
what is the speed formula?
