Summary
Highlights
The position-time graph shows a parabolic curve during acceleration, a straight line with constant positive slope during constant velocity, and another parabolic curve as it decelerates. The slope of this graph represents velocity; a changing slope indicates changing velocity (acceleration/deceleration), while a constant slope indicates constant velocity.
The velocity-time graph displays a positive slope during positive acceleration, a zero slope during constant velocity, and a negative slope during negative acceleration. The slope of this graph represents acceleration. The area under the velocity-time curve represents the distance traveled; this is used to calculate the total distance covered during each phase of the train's journey.
The acceleration-time graph shows constant acceleration during each phase (positive, zero, and negative), indicated by zero slopes on the graph. The area under the acceleration-time curve represents the change in velocity. Positive area signifies increasing velocity, zero area means velocity is constant, and negative area signifies decreasing velocity.
