Chapter 3.1

Position velocity acceleration


What You'll Learn

Recognize that velocity is the derivative of position with respect to time
Calculate acceleration as the derivative of velocity with respect to time
Determine when a particle is at rest, moving forward, or moving backward using velocity signs
Analyze whether a particle is speeding up or slowing down by comparing velocity and acceleration signs
Apply derivatives to interpret motion graphs and calculate total distance traveled

What You'll Practice

1

Finding velocity and acceleration functions from position functions

2

Determining particle motion direction and rest points from velocity values

3

Calculating total distance traveled along a straight line

4

Analyzing speeding up vs. slowing down using velocity and acceleration signs

Why This Matters

Understanding rectilinear motion connects calculus to real-world physics, from analyzing car braking distances to modeling rocket trajectories. These derivative relationships between position, velocity, and acceleration form the foundation for mechanics in engineering and physics courses.
