Velocity-Time Graphs Quiz

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

• Displacement

• Final velocity

• Acceleration

If a section of a velocity-time graph has a slope of zero, what can be inferred about the object's motion?

• The object is decelerating

• The object is accelerating

• The object is stationary

• The object is moving at a constant velocity

How do you calculate the area under a velocity-time graph to find displacement?

• By using the average velocity

• By using geometry to calculate the area of shapes under the graph

• By using the y-intercept of the graph

• By using the slope of the graph
