Analyzing Velocity-Time Graphs

In this video, Mr. Post explains how to determine total displacement using a velocity-time graph. He introduces two methods: the kinematic equations and the area under the graph method. The video focuses on the latter, demonstrating how to calculate displacement by finding the area of rectangles and triangles under the graph. The total displacement is calculated by summing these areas, and the video concludes with a comparison of the two methods.
