How can a position-time graph show if an object has constant acceleration? a. by showing distance over time c. by showing distance over direction b. by showing direction over time d. by showing velocity over distance

_Award brainliest if helped!
a. By showing distance over time

On the Position-Time graph, you can only see the position of the object at the time, after which we use the graph to calculate distance/time and acceleration .
We use the can Slope of the graph to determine acceleration as well .
