Velocity Formula (v = u + at)
v = u + a·t
What it means
Find the final velocity of an object under constant acceleration, given its starting velocity, acceleration, and time.
Variables
| Symbol | Quantity | SI unit |
|---|---|---|
v | final velocity | m/s |
u | initial velocity | m/s |
a | acceleration | m/s² |
t | time | s |
Worked example
Given u = 0 m/s, a = 3 m/s², t = 5 s, solve for v:
v = 15 m/s
