Speed, Distance, Time and Acceleration

The video tutorial explains the concepts of speed and acceleration, crucial in physics. Speed is defined as the rate of change of distance, calculated by dividing distance by time. Examples include calculating the speed of a car and a sprinter. Acceleration is the rate of change of speed, calculated by dividing the change in velocity by time. Examples include a bus and a cheetah's acceleration. The video also covers positive and negative acceleration, represented by the gradient on a speed-time graph.
