The area covered by a velocity-time graph
Explanation:
One important graphical method to the solution of displacement of an object is find the area covered by the curve. Displacement is the distance covered by a body during a particular period in time.
- A velocity-time graph has velocity on the vertical axis and time on the horizontal axis.
- With acceleration, the curve takes shapes and changes. There are periods of no acceleration,constant velocity, deceleration often observed on a velocity-time graph.
- Using this, one can determine the displacement of an object looking for the area of the shape the curve covers.
