Velocity Time Graphs

• What can the acceleration of an object be calculated from?

  The gradient of a velocity-time graph
• What does an object accelerating at a constant rate produce on a graph?

  A straight line on the graph
• What type of line does an object accelerating at a non-constant rate produce on a graph?

  A curve on the graph
• How does the graph differ for constant acceleration versus non-constant acceleration?

  Constant acceleration produces a straight line; non-constant produces a curve
• If an object is accelerating at a constant rate, what does this imply about its velocity-time graph?

  It will be a straight line
• What does an increasing rate of acceleration indicate on a velocity-time graph?

  It will produce a curve
• What does the gradient of a velocity-time graph represent?

  The acceleration of the object
• What type of graph represents velocity over time?

  Velocity-time graph
• What does a straight line on a velocity-time graph indicate?

  Constant acceleration
• How can you tell if an object is accelerating at a constant rate from its graph?

  The graph will show a straight line
• If the velocity-time graph of an object is curved, what can be inferred about its acceleration?

  The acceleration is changing
• What does a curve on a velocity-time graph indicate about the object's motion?

  The object is accelerating at a non-constant rate
