### Educational Content for Velocity-Time Graph Analysis #### Graph Description The provided graph is a velocity-time graph that illustrates the velocity of an object over a period of time from 0 to 12 seconds. The x-axis represents time in seconds (s), while the y-axis represents velocity in meters per second (m/s), ranging from -100 to 100 m/s. - **0 to 2 seconds**: The object's velocity increases linearly from 0 to 40 m/s. - **2 to 6 seconds**: The object maintains a constant positive velocity of 40 m/s. - **6 to 10 seconds**: The object's velocity decreases linearly from 40 m/s to -60 m/s. - **10 to 12 seconds**: The object's velocity continues to decrease linearly from -60 m/s to -100 m/s. #### Questions and Interactive Content 1. **The acceleration when this object reaches the 1 second mark is:** - Answer: The rate of change of velocity per second is 40 m/s². 2. **What is the acceleration of the object at the 4 second mark?** - Answer: Since the velocity is constant, the acceleration is 0 m/s². 3. **What is the speed of the object at the 8 second mark?** - Answer: The speed (absolute value of velocity) is 20 m/s. 4. **At what point is our object moving backward?** - Answer: After 6 seconds, as the velocity becomes negative. 5. **What does this object do at the 9 second mark?** - Answer: [Select] The object is moving at a negative velocity of -20 m/s, indicating it is moving backward. This analysis helps students understand the relationship between velocity, time, and acceleration, and how to interpret different sections of a velocity-time graph.
