Understanding Position vs Time Graphs

What does constant velocity imply about an object's motion?

• The object changes direction frequently.

• The object is accelerating.

• The object maintains the same speed and direction.

• The object is decelerating.

In a position vs time graph, what does the slope represent?

• Time

• Distance

• Velocity

• Acceleration

What does a steeper slope on a position vs time graph indicate?

• The object is moving slower.

• The object is moving faster.

• The object is stationary.

• The object is changing direction.

What does a zero slope on a position vs time graph mean?

• The object is moving forward.

• The object is not moving.

• The object is moving backward.

• The object is accelerating.

How is the direction of motion indicated on a position vs time graph?

• By the length of the line

• By the sign of the slope

• By the thickness of the line

• By the color of the line

What does a positive slope on a position vs time graph indicate?

• The object is accelerating.

• The object is stationary.

• The object is moving forward.

• The object is moving backward.

If car A has a steeper slope than car B on a position vs time graph, what can be inferred?

• Car A is moving in the opposite direction.

• Car A is moving slower than car B.

• Car A is stationary.

• Car A is moving faster than car B.

What does a negative slope on a position vs time graph indicate?

• The object is moving backward.

• The object is accelerating.

• The object is moving forward.

• The object is stationary.

How can you determine if two objects are moving in the same direction on a position vs time graph?

• They have different slope steepness.

• They have the same slope sign.

• They have the same slope steepness.

• They have different slope signs.

What does it mean if two lines intersect on a position vs time graph?

• The objects have stopped moving.

• The objects are moving in opposite directions.

• The objects are at the same position at the same time.

• The objects are moving at the same speed.
