An object moves at a constant speed of 6 m/s. This means that the object:
increases its speed by 6 m/s every second
decreases its speed by 6 m/s every second
doesn't move
moves 6 meters every second
If an object is moving with a constant, positive velocity, the graph of position vs. time is:
a curved lined
a straight, horizontal line
a straight line with a positive slope
a straight line with a negative slope

they would both fall at the same speed
objects do not fall in a vacuum

Betsy the busy bee started at the yellow flower (A) then traveled to the blue flower (B), and next she went to the purple flower (D). She enjoyed the blue flower (B) so much she returned. Calculate Betsy’s total distance and displacement.
distance = 15.4 m
displacement = 15.4 m
distance = 15.4 m
displacement = 4 m
distance = 9.7 m
displacement = 4 m

4 sigfigs
5 sigfigs
1 sigfig
the proper way to express 34567.01 in scientific notation WITH three significant figures is...
346 x 102
3.45 x 104
3.46 x 104
350
What is the proper way to report this calculation ?
17.34 / 3.45?
5.026 because the 17.34 has the most sigfigs
5.03 because the 3.45 has the fewest sigfigs
5.026087 because you need the most decimal places for accuracy
5 because you should round the final answer to the nearest whole number
