SUMMARY
This discussion focuses on understanding rectilinear motion, specifically the relationships between position, velocity, and acceleration of a particle. The key points include that a particle moves right when its position (x value) is increasing and left when it is decreasing. The particle is at rest when the tangent to the position graph x(t) is horizontal. Additionally, the acceleration a(t) is defined as the derivative of the velocity v(t), which can be graphed by estimating the slope of the velocity graph at various points.
