Average Velocity Formula — the NEET Physics formula with its derivation, variables, validity constraints and worked solver.
Average Velocity Formula General kinematics for any type of motion (constant or non-constant acceleration), provided the time interval is finite and non-zero. Define displacement x as x final - x initial. Define time interval t as t final - t initial. Define average velocity as the ratio of total displacement to total time. t > 0 Confusing average velocity with average speed (total distance / total time). Assuming average velocity is always (v initial + v final) / 2 (this is only true for constant acceleration). Believing average velocity must be positive (it is a vector and can be negative in 1D motion).
