CIE A Level Physics复习笔记2.1.3 Area under a Velocity-Time Graph

The velocity-time graph of a vehicle travelling with uniform acceleration is shown in the diagram below.

Calculate the displacement of the vehicle at 40 s.

Always check the values given on the y-axis of a motion graph - students often confuse displacement-time graphs and velocity-time graphs.The area under the graph can often be broken down into triangles, squares and rectangles, so make sure you are comfortable with calculating area!
