Physics: Linear Motion Review Flashcards
Average speed/ velocity
average of all instantaneous speeds/ velocities
on a velocity vs. time graph, contact with the 0 line represents:____
a velocity of 0
on a velocity vs. time graph: signs opposite=____
slow down
Vector/ ex.:
quantity that has both a magnitude (amount) and a direction ex.: displacement, velocity, acceleration
on a position vs. time graph, a straight line represents:____
a stationary object
slope of velocity graph:____
acceleration
Instantaneous speed/ velocity
the speed/ velocity at a given instant
on a velocity vs. time graph: acceleration is determined by:____
the slope being + or -
how is velocity written in equations
_m/s
Scalar/ ex.:____
quantity that has a magnitude (amount) but no direction ex.: distance, speed
slope (rise/run)=
change in x/time= velocity
on a distance vs. time graph, what direction is negative and which is positive
west= -
east= +
on a position vs. time graph, when is a velocity positive or negative?
+ velocity: above the 0 line - velocity: below the 0 line
slope of distance graph:____
velocity
how is position written in equations
_unit of measure (i.e.: meters, inches, miles)
