You're driving and notice a siren - oh NO! You're being pulled over for speeding. You glance at your speedometer to determine your:
instantaneous speed
average speed
velocity
constant speed
What does the slope of this graph represent?
position
time
velocity
distance
The positive slope on this graph indicates that the object is:
moving forward.
increasing speed.
climbing up a ramp.
changing.
Which of the following units does NOT describe speed?
m/s
mi/hr
km/hr
min/m
Which of the following speed units is NOT from the SI system?
mi/hr
km/hr
cm/s
m/min
The average speed for an object in motion can be determined by:
dividing the total time by the total distance
dividing the total distance by the total time
calculating a mathematical average (mean) of speed values
looking at the exact speed an object is going at a certain point in time
How does velocity differ from speed?
Velocity uses different units.
Velocity is associated with a sense of direction.
Velocity is always negative and speed is always positive.
It doesn't; they are identical concepts.
Which of the following is NOT a velocity value?
+15 m/s
15 m/s north
15 m/s
15 m/s backward
How are distance & displacement different?
They are not; they are identical.
Distance is displacement, but with direction.
Displacement is based on the direction of motion; distance is not.
Distance is only used with velocity.
