**Title: Understanding Velocity-Time Graphs** **Velocity-Time Graph Analysis** In the graph provided, we can analyze the motion of an object over a period of time. The graph plots the velocity (v) of the object in meters per second (m/s) on the vertical axis and the time (t) in seconds (s) on the horizontal axis. **Detailed Explanation:** - **Axes and Units:** - **Vertical Axis (Velocity, v):** This axis represents the velocity of the object in meters per second (m/s). The values range from 0 to 1.0 m/s. - **Horizontal Axis (Time, t):** This axis represents the time in seconds (s). The values range from 0 to 0.60 seconds. - **Graph Description:** - The graph starts at the origin (0,0), indicating that the velocity of the object is 0 m/s at 0 seconds. - As time progresses, the velocity increases linearly, reaching its peak velocity of 1.0 m/s at 0.20 seconds. - From 0.20 seconds to 0.40 seconds, the velocity decreases linearly, returning to 0 m/s at 0.40 seconds. - After 0.40 seconds, the velocity remains constant at 0 m/s until 0.60 seconds. **Interpretation of the Motion:** 1. **Acceleration Phase (0 to 0.20 s):** - The object accelerates from rest to a velocity of 1.0 m/s in 0.20 seconds. This is indicated by the upward slope of the graph. 2. **Deceleration Phase (0.20 to 0.40 s):** - The object decelerates back to rest (0 m/s) over the next 0.20 seconds. This is indicated by the downward slope of the graph. 3. **Rest Phase (0.40 to 0.60 s):** - The object remains at rest with a velocity of 0 m/s for the remaining time from 0.40 seconds to 0.60 seconds. This is indicated by the flat line at the bottom of the graph. By analyzing the velocity-time graph, we gain valuable insights into the motion of the object, including its periods of acceleration, deceleration, and constant velocity. Understanding such graphs is crucial for comprehending
