\[v = v_0 + a t\]
Variables
vfinal velocity (m/s)
v0initial velocity (m/s)
aacceleration (m/s²)
ttime elapsed (s)
Description
What is this formula?
This equation calculates the final velocity of an object undergoing constant acceleration during linear motion.
When to use it
Use this formula when acceleration remains constant over time and the initial velocity is known.
Example
If a car starts at 10 m/s and accelerates at 3 m/s² for 5 s:
v = 10 + 3 × 5 = 25 m/s
Applications
Vehicle dynamics, motion prediction, mechanical engineering, robotics, and physics education.
