The linear equation:
directly parallels the equation for the velocity of an object with a constant acceleration:
Therefore, with the velocity on the y-axis and the time on the x-axis, the regression simply gives us the constants for the velocity equation.
The slope of the v vs. t line (the change in velocity
over change in time) is the acceleration. The intercept (the velocity
at time zero) indicates the initial velocity or vi.
