Welcome to our exploration of displacement-time graphs. A displacement-time graph is a fundamental tool in physics that shows how an object's position changes over time. The horizontal axis represents time, usually measured in seconds, while the vertical axis shows displacement, which is the position relative to a reference point, typically measured in meters.
The slope of a displacement-time graph is crucial because it tells us about the object's velocity. A positive slope means the object is moving forward, increasing its displacement over time. A negative slope indicates the object is moving backward, decreasing its displacement. A horizontal line with zero slope shows the object is at rest. The steeper the slope, the higher the velocity.
