Understanding Position-Time Graphs

On a position-time graph, what does the steepest slope indicate?

• The object is moving at its slowest speed.

• The object is moving at its fastest speed.

• The object is accelerating.

• The object is at rest.

Which letter on the graph indicates the object is at rest?

• Letter A

• Letter B

• Letter C

• Letter D

What does a straight line on a position-time graph represent?

• Deceleration

• Acceleration

• Constant velocity

• Changing velocity

How is constant velocity depicted on a position-time graph?

• By a straight line

• By a vertical line

• By a curved line

• By a horizontal line

What does a curved line on a position-time graph indicate?

• The object is moving backward

• The object is at rest

• Changing velocity

• Constant velocity

In which direction is the object moving if the slope is trending back towards the origin?

• Rightward

• Upward

• Leftward

• Downward

What does a steep slope in the leftward direction indicate?

• The object is accelerating

• The object is at rest

• The object is moving fast

• The object is moving slowly

What is indicated by a curved line on a position-time graph?

• The object is accelerating

• The object is moving at a constant speed

• The object is decelerating

• The object is at rest

Why is it important to check the axes on a graph?

• To understand the scale of the graph

• To determine the color of the graph

• To know what is being measured

• To find the origin

What should you look for to identify acceleration on a position-time graph?

• A vertical line

• A straight line

• A horizontal line

• A curved line
