What does a flat horizontal line mean on a position vs time graph?
moving fast
object in motionless
gettin faster
coming back to start
Which of the following accurately contrasts velocity and speed?
speed is distance traveled in a certain amount of time. Velocity is time traveled in a certain distance
speed is distance traveled in a certain time. Velocity is speed in a specific direction
Velocity is distance traveled in a certain time. Speed is velocity in a certain direction
velocity is distance traveled in a certain time. Soeed is how fast you're going
Acceleration is defined as the CHANGE in
time it takes for one place to move to another place.
velocity of an object.
distance divided by the time
velocity divided by the time
What is the distance the mouse travelled? What is the mouse's displacement?
7 m; -1 m
-1 m; 7 m
8 m; 0 m
0 m; -1 m
What is a difference between distance and displacement
Distance is measured in seconds and displacement is measured in meters
Distance is always shorter than displacement
Displacement can be equal to zero if the object ends in the place it began in; distance counts every step taken
Distance can be equal to infinite when only a small distance has been travelled

0.625 m
100,000 m
1.6 m
650 m

2.5 m/s
0.4 m/s
20 m/s
