Analyzing Speed-Time Graphs and Their Implications in Motion

The video tutorial explains speed-time graphs, focusing on the relationship between speed and time. It covers how to interpret different graph lines, such as horizontal lines indicating constant speed and straight lines showing acceleration or deceleration. Examples are provided to calculate acceleration and deceleration using graph gradients. The video also demonstrates how to calculate total distance and average speed using the area under the graph. The tutorial concludes with a call to action for viewers to subscribe and support the channel.

What does the gradient of a speed-time graph represent?
