• the object never stopped

• the object sped up on the way back to the origin

• the object sped up in the forward direction

Which describe the motion correctly?

• the object never changed speed

• the object returned to the start

• the object stopped for awhile

• the object always went forward

Which is TRUE?

If the dots represents 1-second intervals, which of these is the best mathematical model to represent the motion map?

• x = (2 m/s)t + 2 m

• x = (0.5 m/s)t + 2 m

• x = (2 m/s)t + 0 m

• x = (0.5 m/s)t + 7 m
