1.1.2 Distance-Time Graphs

• A straight line on a distance-time graph indicates constant speed.


  True
• What does a horizontal line on a distance-time graph indicate?

  Stationary motion
• What does the horizontal axis of a distance-time graph represent?

  Time
• What does the gradient of a distance-time graph represent?

  Speed
• An accelerating object on a distance-time graph is represented by a curved line that becomes steeper
• Match the type of motion with its distance-time graph shape:

  Constant Speed ↔️ Straight line

  Accelerating ↔️ Curved line, steeper

  Stationary ↔️ Horizontal line
• The vertical axis of a distance-time graph represents distance
• The speed of an object can be calculated from a distance-time graph by finding the gradient
• How can the speed of an object be calculated from a distance-time graph?

  By finding the gradient
• Match the motion type with its distance-time graph shape:

  Stationary ↔️ Horizontal line

  Decelerating ↔️ Curved line, flatter
• What does the shape of a distance-time graph reveal about an object's motion?

  Type of motion
• What does the vertical axis of a distance-time graph represent?

  Distance
• How is the gradient of a distance-time graph calculated?

  Change in Distance / Change in Time
• A straight line on a distance-time graph indicates constant speed


  True
• A distance-time graph shows how the distance travelled by an object changes over time
• A curved line flattening on a distance-time graph indicates deceleration.


  True
• A distance-time graph can be used to determine an object's speed and acceleration.


  True
• Steps to analyze a distance-time graph:

  1️⃣ Identify the axes

  2️⃣ Examine the shape of the graph

  3️⃣ Determine the type of motion

  4️⃣ Calculate the speed

  Change in Distance / Change in Time
• A horizontal line on a distance-time graph indicates the object is stationary


  True
• The gradient of a distance-time graph represents the speed
• A curved line that gets flatter on a distance-time graph indicates decelerating

  4 m/s
• A curved line that gets steeper on a distance-time graph indicates acceleration


  True
• In a distance-time graph, the horizontal axis represents time
• Match the motion type with its distance-time graph shape:

  Accelerating ↔️ Curved line, steeper

  Decelerating ↔️ Curved line, flatter
• A flatter gradient on a distance-time graph indicates a lower speed


  True
• Match the motion type with its distance-time graph shape:

  Constant Speed ↔️ Straight line

  Stationary ↔️ Horizontal line

  Decelerating ↔️ Curved line, flatter
