Question

2.3 position vs. time graphs

1. what kind of motion would create a position graph like the one shown?

position vs. time

time (s)
a. uniform motion
b. any motion that accelerates
c. motion that stops and then starts
d. motion that has constant velocity

Explanation:

In a position - time graph, uniform motion (constant velocity) is represented by a straight - line graph. An accelerating motion would have a curved graph. The given graph is curved, which indicates a change in velocity over time. This is characteristic of any motion that accelerates.

Answer:

b. any motion that accelerates
