Understanding Velocity Time Graphs

The video tutorial explains how to represent the velocity of an object graphically using velocity-time graphs. It covers the basics of these graphs, including the axes and units used. The tutorial provides examples of increasing, constant, and decreasing velocities. It then demonstrates constructing a velocity-time graph for a BMW test, showing uniform acceleration, constant speed, and deceleration. The video also explains how to calculate acceleration from the graph's gradient, highlighting the relationship between slope steepness and acceleration. Finally, it analyzes the BMW's final deceleration.
