Formula Used in “Heisenberg’s Uncertainty Principle Calculator”
The Heisenberg Uncertainty Principle is a fundamental concept in quantum mechanics that defines a limit to the precision with which certain pairs of physical properties, known as complementary variables or conjugate variables, can be simultaneously known. The principle can be expressed broadly through the following formula:
Δx · Δp ≥ ℏ/2
In this equation:
- Δx represents the uncertainty in position
- Δp signifies the uncertainty in momentum
- ℏ is the reduced Planck’s constant, approximately equal to 1.055 x 10-34 Js
Step-by-Step Breakdown of the Formula
This formula can be broken down into its components for better understanding:
- Identify the uncertainty in position (Δx): This is the degree of uncertainty regarding the particle’s position.
- Determine the uncertainty in momentum (Δp): Momentum is calculated as the product of mass (m) and velocity (v). Therefore, Δp can be expressed as Δp = m·Δv, where Δv is the uncertainty in velocity.
- Substitute values into the formula: Once you have your values for Δx and Δp, plug them into the inequality to evaluate.
- Analyze results: If your product Δx · Δp meets or exceeds ℏ/2, it is consistent with the Heisenberg Uncertainty Principle.
Example Calculation
To understand how to use the Heisenberg Uncertainty Principle, let’s consider a practical example:
Scenario
Suppose we are trying to measure the position of an electron confined in a box with a known uncertainty in its position (Δx) of 1 x 10-10 m, and we want to find the uncertainty in its momentum (Δp).
Known Values
| Variable | Value |
|---|---|
| Δx (Uncertainty in position) | 1 x 10-10 m |
| ℏ (Reduced Planck’s constant) | 1.055 x 10-34 Js |
Calculation Steps
- Calculate the maximum uncertainty in momentum (Δp):
Using the formula: Δp ≥ ℏ/ (2 · Δx)
Substituting values:
Δp ≥ 1.055 x 10-34 Js / (2 · 1 x 10-10 m)
Δp ≥ 5.275 x 10-25 kg·m/s
Conclusion
This illustrates that the uncertainty in momentum (Δp) must be at least 5.275 x 10-25 kg·m/s for our electron given the position uncertainty we’ve specified. The Heisenberg Uncertainty Principle demonstrates that, as we narrow the uncertainty in one measurement (position), the uncertainty in the complementary measurement (momentum) must increase.

The mass of the particle represents its resistance to acceleration when a force is applied. It is a critical component in determining the particle’s momentum.
Example: For an electron, the mass is approximately 9.11 x 10-31 kg.
2. Velocity (v)
Velocity refers to how fast the particle is moving in a given direction. This value is essential for calculating the momentum of the particle.
Example: If an electron is moving at 2.5 x 106 m/s, this is the velocity you would input.
3. Standard Deviation of Position (Δx)
This represents the degree of uncertainty in the particle’s position. A smaller Δx leads to a larger uncertainty in momentum.
Example: If you estimate the position uncertainty to be 1 x 10-10 m, input that value.
How to Interpret the Results
Upon submission, the Heisenberg’s Uncertainty Principle Calculator will output uncertainties related to the particle’s momentum and energy.
1. Uncertainty in Momentum (Δp)
This value indicates the uncertainty associated with the momentum of the particle. According to Heisenberg’s principle, lowering the uncertainty in position increases the uncertainty in momentum.
Common Mistake: Miscalculating the inputs can lead to inaccurate Δp values. Always double-check your mass, velocity, and position uncertainty before submitting.
2. Uncertainty in Energy (ΔE)
This output reflects the uncertainty in the energy of the particle. High momentum uncertainty typically results in high energy uncertainty.
Common Mistake: Be attentive to unit conversions; inconsistency can cause erroneous calculations. Ensure all values are within SI units (kg, m/s).
