Distance Time Graphs for Accelerated Motion

The video tutorial explains how to interpret distance-time graphs for accelerated motion. It begins with a recap of constant speed graphs, where speed is represented by the gradient. The tutorial then introduces scenarios where speed is not constant, indicating acceleration. To find speed at a specific time, a tangent is drawn on the graph, and its gradient is calculated using rise over run. This method is demonstrated with an example, showing how to determine the speed of an object at a given time. The tutorial concludes with a summary of the key concepts covered.

What does an increasing gradient on a distance-time graph indicate about the object's motion?
