GCSE Secondary Maths Age 13-17 - Graphs: Speed/Time Graph - Explained

The video tutorial explains how to interpret a speed-time graph for a car journey. It covers calculating velocity using the area under the graph, specifically a trapezium, and describes acceleration at different stages of the journey. The tutorial emphasizes the importance of unit conversion and understanding graph gradients to determine acceleration and deceleration. Key points include calculating velocity, understanding acceleration, and the significance of graph areas.
