Free Fall - Final Velocity
Free Fall - Final Velocity
\[v = g t\]
Variables
v = final velocity (m/s)
g = gravitational acceleration (m/s²)
t = time of fall (s)
Description
What is this formula?
This equation calculates the final velocity of an object in free fall starting from rest under constant gravitational acceleration.
When to use it
Use this formula when an object is dropped without initial velocity and air resistance is negligible.
Example
If an object falls for 4 s on Earth:
v = 9.81 × 4 = 39.24 m/s
Applications
Physics education, gravitational motion analysis, safety calculations, drop testing, and engineering studies.
