Forces and Motion
This is a push or pull on an object.
DOUBLE: This is the scientific word for something that pulls.
TRIPLE: This is the scientific word for something that pushes.
What is a force?
DOUBLE: What is attractive?
TRIPLE: What is repulsive?
DOUBLE: What is the acceleration due to this of all objects near Earth?
What is gravity?
DOUBLE: 9.8 m/s/s
This is the energy of motion.
What is kinetic energy?
This is a transfer of energy, but not matter, from one place to another.
DOUBLE: This is one, non-repeated instance of this.
What is a wave?
DOUBLE:What is a wave pulse?
For 100 points each, name scientists or engineers we learned about and a brief description of who they are.
Possible answers:
Isaac Newton, Nikola Tesla, Dalton, Syukuro Manabe, Grant Imahara, Neil DeGrasse Tyson, Mae Jemison, Lewis Latimer, Aprille Ericsson, Ursula Burns, Guion Bluford... and many more!
This law states that force is equal to mass times acceleration.
What is Newton's Second Law?
This noncontact force only occurs between certain materials and magnetic objects. They may be attractive or repulsive.
DOUBLE: These three metals are impacted by magnetism.
What is magnetism?
DOUBLE: What are iron, cobalt, and nickel?
This is the ability to cause motion or change.
What is energy?
The matter in this type of wave moves parallel to the energy.
What is a longitudinal wave?
This is the name for forces with a net force of zero.
DOUBLE: This is the name for net forces with a net force not equal to zero.
What are balanced forces?
DOUBLE: What are unbalanced forces?
This law states that at object at rest stays at rest, and an object in motion stays in motion, unless acted on by an unbalanced force.
DOUBLE: What is the other word for this concept, used by Galileo?
What is Newton's First Law?
DOUBLE: Inertia.
This noncontact force only occurs between charged particles. They may be attractive or repulsive.
DOUBLE: With these forces, opposites _______________ while the same _____________.
What is electric forces?
DOUBLE: What is attract, repel?
This is the total amount of kinetic energy in the particles of a substance.
DOUBLE: This is the average kinetic energy of the particles of a substance.
What is thermal energy?
DOUBLE: What is temperature?
This matter in this type of wave moves perpendicular to the energy in this wave.
DOUBLE: This is the shape of one cycle of this type of wave.
What is a transverse wave?
DOUBLE: What is an S-curve?
This is the point of view on the speed and direction of an object compared to its reference point.
This law states that every action has an equal opposite reaction.
What is Newton's Third Law?
This kind of diagram is used to show predictions of forces that would act on a object.
DOUBLE: These are the three types of this diagram.
What are force fields?
DOUBLE: What are gravitational, electric, and magnetic fields?
When energy changes form, it is _____________, while when it moves from one object to another it is ____________.
What are converted and transfered?
This is the matter a mechanical waves moves through.
What is medium?
These two forces cause a flow of electrons.
What are magnetism and electricity?
This force slows a moving object by converting its kinetic energy into thermal energy. It also keeps an object in place if not enough force is applied.
What is friction?
As this increases, the strength of a noncontact force deacreases.
What is distance?
DOUBLE: These are the five types of this energy we learned about in class.
What is potential energy?
DOUBLE: What are chemical, gravitational, elastic, electric, and magnetic?
These are three of the ways to measure a wave.
DOUBLE: Define each term.
Possible answers: What are frequency, wavelength, amplitude, and velocity?
______________ are how you know an engineering solution is successful, while _________________ are the obstacles to success.
DOUBLE: This type of engineering process uses many prototypes and evaluates hypotheses with each one.
What are criteria and constraints?
DOUBLE: What is iterative engineering?
