light and sound Flashcards
(32 cards)
an astronuat is far away from an obkect in the universe. he does have a baseball. however. he throws the baseball the baseball does what?
-
object in motion …
stays in motion
an atronuat is near the earth, just outsid the atmosphere. she also has a baseball. when she throws it what happens to the ball?
curves and speeds up
what is in a name?
- size
- agent
- direction
if our astornuats ball curved and sed up is a force acting on it? if so what force?
yes, gravity
Reading 1 & 2 Know the disciplines that will contribute to our overall course, and know roughly
what their roles will be in the grand process of perception. Educated estimates (Fermi
Estimates).
-
Know the Perception Cycle
Know and recognize the names of the steps in the perception cycle.
Be able to apply them to an example accurately and completely.
Know how Knowledge differs.
-
Know what an Operational Definition is, and be able to recognize (or even make) one.
-
Be able to name or recognize the 4 basic quantities (fundamental quantities).
-
Be able to recognize the quantities that are derived from the fundamental ones which we expect
to use in the term.
-
Recognize and be able to use accurately the terms used to describe motion.
-
Understand and be
able to use the operational definitions for these derived quantities; speed, velocity, acceleration.
-
what are the steps in the persception cycle?
perception>become conciously aware of it
recongnition>
action>
environmental stimulus>
attended stimulus>
stimulus receptors>
transduction>take the waves that go into ear and convert them in as a signal brain can understand
processing>two bits of information to reach a conclusion
Know what an Operational Definition is, and be able to recognize (or even make) one.
-Tells us how to measure things and states or implies the steps needed to observe or measure a property. Steps and requirements to define a college sophmore like so many credits and hours.
Be able to name or recognize the 4 basic quantities (fundamental quantities).
- Length
- time
- mass=how much inside something like atoms and protons and nuetrons
- charge=protons nuetrons are negatively charged
what is speed?
-
what is accleration?
-
what is velocity?
-change in the position in distance and time the measure of veolcity
Recognize and be able to use accurately or calculate from the operational definitions the
properties of matter. (Quantities used to measure matter: mass, length, area, volume, density. However, I will
freely give you “round” shape formulae for area and volume if you need them. I avoided them this time.)
-
Know what Newton’s Laws of motion are.
1.
2.
3.
4.
what is net force?
net force=left over and something is accelerating
work=
force x displacement
can work be negative?
yes, because process as it’s moving the gravity doing negative work and person pulling up object is positive
a person holds a bucket of water is work done?
