Distance - Time Graphs

How can you determine the speed from a distance-time graph?

• The speed is the area under the curve.

• The speed is the slope of the line; steeper slopes indicate higher speeds.

• The speed is the total distance divided by time.

• The speed is the y-intercept of the graph.

What does a flat line followed by a steep line indicate on a distance-time graph?

• The object was at rest and then started moving at a constant speed.

• The object was moving at a constant speed and then stopped.

• The object was accelerating and then decelerated.

• The object was moving at varying speeds throughout.

What does a straight line with a negative slope indicate on a distance-time graph?

• Return Home (negative slope)

• Increase in speed

• Constant speed

• Decrease in distance

What does it mean if the distance-time graph has a line that is straight but not horizontal?

• The object is moving at a constant speed.

• The object is at rest.

• The object is accelerating.

• The object is moving at a variable speed.

How can you tell if an object is accelerating on a distance-time graph?

• The line will curve upwards, indicating increasing distance over time.

• The line will be straight and horizontal, indicating constant speed.

• The line will curve downwards, indicating decreasing distance over time.

• The line will be straight and diagonal, indicating constant acceleration.

What is the significance of the x-axis on a distance-time graph?

• It represents the distance traveled.

• It represents the speed of the object.

• It represents the time elapsed.

• It represents the acceleration of the object.

What does a straight line with a positive slope indicate on a distance-time graph?

• Constant Speed (positive slope)

• Increasing Speed

• Decreasing Speed

• No Movement

What does a curve that slopes downwards indicate on a distance-time graph?

• Acceleration (increasing speed)

• Constant speed

• Deceleration (decreasing speed)

• No movement

What is the formula for calculating speed from a distance-time graph?

• Speed = Distance + Time

• Speed = Distance - Time

• Speed = Distance / Time

• Speed = Distance * Time

What does a distance-time graph with a line that returns to the origin indicate?

• The object has returned to its starting point.

• The object is moving at a constant speed.

• The object is accelerating.

• The object is moving away from the starting point.
