About Decay Energy Calculator (Formula)
Decay energy is the energy released during the radioactive decay of a particle. This energy can be calculated by considering the difference in mass before and after the decay process. Understanding decay energy is essential in fields such as nuclear physics and radiation therapy. The Decay Energy Calculator simplifies this complex calculation, providing a quick and accurate way to find the energy released during decay.
Formula
The formula for calculating decay energy is derived from Einstein’s famous equation, E = mc², and is given as:
Decay Energy (E) = (Mass before Decay – Mass after Decay) * c²
Where:
- E is the decay energy in joules,
- Mass before Decay is the mass of the particle before decay (in kilograms),
- Mass after Decay is the mass of the particle after decay (in kilograms),
- c is the speed of light (approximately 3.00 × 10^8 m/s).
How to Use
To use the Decay Energy Calculator, follow these simple steps:
- Enter the mass before decay (in kilograms).
- Enter the mass after decay (in kilograms).
- The calculator applies the formula: (Mass before Decay – Mass after Decay) * c².
- The result will show the decay energy in joules.
This process helps you quickly determine the energy released during particle decay.
Example
Suppose you are calculating the decay energy of a particle with the following values:
- Mass before Decay: 2.5 × 10^-27 kg,
- Mass after Decay: 2.4 × 10^-27 kg.
- Input the values into the formula:
Decay Energy (E) = (2.5 × 10^-27 – 2.4 × 10^-27) * (3.00 × 10^8)². - Decay Energy (E) = (0.1 × 10^-27) * 9 × 10^16.
- Decay Energy (E) = 9 × 10^-12 joules.
Thus, the energy released during the decay is 9 × 10^-12 joules.
