Rockets
This law, often associated with rockets, states that for every action there is an equal and opposite reaction
What is Newton's 3rd law?
This is a basic electrical circuit component that resists the flow of electric current.
What is a resistor?
This the term for a device that generates electricity using magnets
What is a generator?
This is the term for the number of vibrations or cycles of a sound wave that occur in one second, and it is measured in Hertz
What is frequency?
This is the first step in the engineering design process, where engineers identify a problem or a need.
What is defining the problem?
This is the force that a rocket must overcome to lift off from the Earth’s surface; it’s the force that pulls objects towards the center of the Earth.
What is gravity?
This type of circuit has only one path for current to flow, so if one component fails, the whole circuit stops working.
What is a series circuit?
This is the most common type of power plant that is very reliable but produces a lot of air pollution
What is a coal power plant?
This phenomenon occurs when sound waves bounce off a surface, causing the sound to be heard again.
What is an echo?
In this step, engineers gather information and requirements about the problem and the needs of the potential users.
What is researching or background research?
This is the term that describes the force that goes against gravity and lifts the rocket off the ground
What is thrust?
This term refers to the flow of electric charge in a circuit, and it is measured in amperes or amps.
What is current?
This is the most common type of generator in a power plant
What is a steam turbine?
This property of sound determines its loudness and is measured in units called decibels (dB).
What is amplitude or volume?
This step involves coming up with multiple solutions or ideas to address the defined problem.
What is brainstorming or generating concepts?
This phenomenon, experienced by astronauts during launch, is the force exerted on a body as a result of acceleration, often measured in multiples of the gravitational acceleration g.
What is a G-force?
In this type of circuit, there are multiple paths for the current to flow. If one component fails, the rest of the circuit can still work.
What is a parallel circuit?
This a term for a device that "steps up" or steps down voltage in entering or leaving power lines
What is a transformer?
This term refers to the type of wave a sound wave is
In this phase, engineers create a model or prototype of the chosen design and test it to see if it meets the defined requirements.
What is building a prototype and testing?
This is how high a bottle rocket was launched, using the equation (d=1/2at^2), that spent a total of 16 seconds in air
What is 313.6m?
Using Ohm's Law, if a resistor with a resistance of 5 ohms has a current of 2 amperes flowing through it, this is the voltage across the resistor.
What is 10 volts?
This is a type of power plant that generates heat to power a steam turbine through radioactive decay and is extremely reliable and produces little air pollution.
What is a nuclear power plant?
This term refers to the change in frequency and wavelength of a sound wave as observed by a person who is moving relative to the source of the sound.
What is the doppler effect?
This is the iterative part of the engineering design process, where engineers use the results of testing to make informed decisions, and improve the design before testing again.
What is evaluating and refining the design?
