Free Fall Calculator
Time, Height, and Velocity
Calculate free fall time, height, and velocity for objects in gravitational acceleration.
Free Fall Parameters
m
m/s²
Default: 9.81 m/s² (Earth)
Free Fall Formulas
t = √(2h/g)
h = ½gt²
v = gt
Note
This calculator assumes no air resistance. Real-world results may vary due to drag forces.
Example Falls
10-story Building
~30 m → 2.5 seconds
Skydiving (initial)
4000 m → 28.6 seconds
Cliff Diving
20 m → 2.0 seconds
About Free Fall
Free fall is motion under gravity alone, with no air resistance. All objects fall at the same rate regardless of mass.
- Constant acceleration (g)
- Velocity increases linearly
- Independent of mass
Applications
- Physics experiments
- Safety calculations
- Skydiving and BASE jumping
- Engineering design
- Ballistics
