Reading Position Time Graphs

What does the slope of a position-time graph represent?

• Distance

• Displacement

• Velocity

• Acceleration

Consider the graph shown below. Which description below is consistent with the graph?

• The object moves slowly at a constant speed and then faster at a constant speed.

• The object accelerates in the positive direction and then accelerates more rapidly.

• The object moves forward, changes direction and then accelerates more rapidly.
