About the lecture

In this mini-lecture, we define distance, speed, and acceleration, focusing in particular on: (i) the relationship between speed s and distance d given by s = d/∆t, where ∆t is the change in time, and some examples using this equation; (ii) distance vs. time graphs, where we learn that the speed is the slope of the graph; (iii) speed vs. time graphs, where we learn that the slope of the graph, that is the change in the speed, is the acceleration, and the area under the curve is the distance travelled; and (iv) the relationship between acceleration a and speed s given by a = ∆s / ∆t, where ∆t is the change in time, followed by an example using this equation.
