Today we examined the position time graphs that you created for the marble on the inclined track. We talked about the difference between average velocity (slope between two points) and instantaneous velocity (slope of a line tangent to the graph at a specific point in time). We also talked about acceleration and how to calculate it. Tomorrow we will derive the kinematics equations for constant acceleration and begin using them.
