- Instantaneous velocity: The limit of the average velocity as the time interval approaches zero.
- vx = lim∆t→0 ∆x / ∆t = dx/dt
- The slope of the tangent line on a position-time graph is equal to instantaneous velocity.
- Instantaneous velocity can be positive, negative, or zero.
- Instantaneous speed: Magnitude of the instantaneous velocity
Chapter 2.3 Acceleration
