Physics 2A-G Q&A
Define displacement in your own words. - (correct answer)change in place
If you wake up in the morning, go to school, go to the grocery store, and then return to
the same place where
you woke up, what is your displacement for the day? - (correct answer)0
What kind of quantity is displacement, scalar or vector? - (correct answer)Vector
because it has a magnitude and direction
Can an object's displacement be negative? What does the sign indicate about the
displacement? - (correct answer)yes. left and right
If someone told you that they traveled 50 km east, are they describing the distance they
traveled or their
displacement? How do you know? - (correct answer)displacement because the direction
is there
Can the distance an object travels be negative? - (correct answer)no
When will an object's displacement and distance traveled be different? - (correct
answer)when taking steps in different directions
Draw a vector diagram for a person that walks 3 m north and 5 m east. How would you
determine the
displacement for this person? - (correct answer)use pythang therom
Define time interval in your own words. - (correct answer)different time at multiple points
, Define speed in your own words. - (correct answer)speed is the rate at which an object
covers distence
Why does a car speedometer only have positive values, even though you can move in
reverse? - (correct answer)the direction doesn't matter beccause this is a scarlar
quantity
Fill in the equation for average speed below:
average speed = - (correct answer)total distence divided by total time
Define velocity in your own words. - (correct answer)objects can changge in position or
displacement over change in time
Because velocity is a _____________ quantity, _____________matters. - (correct
answer)scarlar, direction
Fill in the equation for average velocity below:
average velocity = - (correct answer)displacement divieded by time
How does instantaneous velocity differ from average velocity? - (correct answer)the
average velocity tell us the over the entire journey. Instantaneous velocity is the velocity
of an abject at a specific point in time
If you travel at a constant velocity, how does the average velocity compare to the
instantaneous velocity
throughout the trip? - (correct answer)they remmain the same
Will an object's average velocity and average speed always be the same? Explain what
happens when the
