The Physics Height Calculator uses a fundamental physics formula to determine the height from which an object falls based on the time it takes to reach the ground. This calculation is crucial for experiments and applications involving motion and gravity, providing a straightforward way to measure height without direct measurement tools.
Formula of Physics Height Calculator
The formula used by the Physics Height Calculator is:
Where:
- h = height (in meters)
- g = acceleration due to gravity (9.8 m/s² on Earth)
- t = time (in seconds)
This formula assumes that the fall is from rest and that air resistance is negligible. It is a basic equation from kinematics that provides accurate results under these conditions.
Table of General Terms
| Term | Definition | Example Value |
|---|---|---|
| Height (h) | Distance object falls | 10 m |
| Time (t) | Time taken to fall | 1.43 s |
| Gravity (g) | Acceleration due to gravity on Earth | 9.8 m/s² |
This table helps users quickly reference the common parameters involved in height calculations.
Example of Physics Height Calculator
Consider a scenario where you need to calculate how high a bridge is above a river. If a stone takes 2 seconds to hit the water, the height of the bridge can be calculated as follows:
h = (1/2) * 9.8 * (2^2) = 19.6 meters
Most Common FAQs
A1: The calculator is highly accurate under ideal conditions (no air resistance and accurate time measurement).
A2: Yes, but the gravity value (g) must be adjusted according to the gravitational force of the other celestial body.
A3: Ensure accurate timing and use the calculator in environments where air resistance is minimal.
