First Equation of Motion (v = u + at)
jee-mainjee-advancedneet-ug
v = u + at
What each symbol means
| Symbol | What it stands for |
|---|---|
| a | Constant acceleration (m/s²) |
| t | Time interval (s) |
| u | Initial velocity (m/s) |
| v | Final velocity (m/s) |
When to use this
Particle moves in a straight line with constant acceleration a. Same sign convention for u, v, a along the chosen axis.
