Estimate falling speed from time, height, and gravity inputs. View formulas, export results, and study examples with clear physics steps.
| Case | Initial Velocity (m/s) | Gravity (m/s²) | Time (s) | Height (m) | Final Velocity (m/s) |
|---|---|---|---|---|---|
| Example 1 | 0 | 9.81 | 2 | 19.62 | 19.62 |
| Example 2 | 3 | 9.81 | 4 | 90.48 | 42.24 |
| Example 3 | 0 | 1.62 | 5 | 20.25 | 8.1 |
| Example 4 | 5 | 9.81 | 3 | 59.145 | 34.43 |
The calculator uses two standard free fall relations. When time is known, it uses v = u + gt and s = ut + ½gt². Here, v is final velocity, u is initial velocity, g is gravity, t is time, and s is fall distance.
When height is known, it uses v² = u² + 2gs. Rearranging gives v = √(u² + 2gs). Time is then estimated from the same motion relation by solving the vertical motion equation.
This calculator helps physics students, teachers, and problem solvers estimate the velocity of an object during free fall. It supports both time-based and height-based inputs, making it useful for classwork, homework, and quick checks.
The tool also returns related motion values, including distance traveled and average velocity. A plotted graph and progress table make the motion easier to understand and verify step by step. Export options support keeping records for reports, assignments, or lab notes.
Free fall calculations assume motion under constant gravitational acceleration. Air resistance is ignored, which matches many introductory physics problems. You can change gravity to explore motion on Earth, the Moon, or other environments.
It calculates the final velocity of a falling object. It also shows distance, time estimation, average velocity, and a step table for better physics interpretation.
Free fall is motion caused only by gravity. In standard textbook problems, air resistance is ignored so the object accelerates uniformly downward.
Yes. Enter any starting velocity value. Use zero when the object is simply dropped without an initial push.
For Earth, use 9.81 m/s². You may enter another value to model motion on the Moon or in a custom physics problem.
Some problems give time, while others give height. This calculator supports both so you can solve a wider range of free fall questions quickly.
No. The formulas assume ideal free fall under constant gravity. Results are most accurate for textbook models and simplified motion analysis.
The graph helps you visualize how velocity changes with time or height. It makes the motion pattern easier to inspect and explain.
Yes. The page includes CSV and PDF download options, so you can save the calculated output for study notes, reports, or assignments.
