Velocity time graph

• What do velocity-time graphs represent?

  Journeys and changes in velocity
• What does a flat section on a velocity-time graph indicate?

  Travelling at a steady speed
• What does a steeper graph on a velocity-time graph signify?

  Greater acceleration or deceleration
• What do uphill sections on a velocity-time graph represent?

  Positive Acceleration
• What do downhill sections on a velocity-time graph represent?

  Negative acceleration
• What does a curve on a velocity-time graph indicate?

  Changing acceleration
• How is the area under a velocity-time graph interpreted?

  It represents distance traveled
• What are the steps to calculate acceleration from a velocity-time graph?

  1. Identify the change in velocity
  2. Identify the time interval
  3. Use the formula:

  $\text{Acceleration} =$$\frac{\text{Change in velocity}}{\text{Time}}$
• How do you determine the distance traveled from a velocity-time graph?

  1. Calculate the area under the graph
  2. Use appropriate geometric formulas for shapes
  3. Sum areas for different sections if needed
• If a car's velocity-time graph shows a steady speed, what does this imply about the car's motion?

  The car is not accelerating or decelerating
• How can you differentiate between acceleration and deceleration on a velocity-time graph?

  Acceleration is uphill; deceleration is downhill
• If a car travels at a steady speed for 10 seconds, what does the velocity-time graph look like?

  It shows a flat horizontal line
• What would the area under a velocity-time graph represent if the graph is a triangle?

  Distance traveled during that time
• What does a constant acceleration look like on a velocity-time graph?

  A straight line with a positive slope
• What is the unit of measurement for velocity in a velocity-time graph?

  Meters per second (m/s)
• What is the unit of measurement for time in a velocity-time graph?

  Seconds (s)
