Mass-Energy Equivalence Formula:
| From: | To: |
The mass-energy equivalence equation (E = mc²) is a fundamental principle in physics that demonstrates the relationship between mass and energy. It shows that mass can be converted into energy and vice versa, as described in Albert Einstein's theory of special relativity.
The calculator uses the mass-energy equivalence equation:
Where:
Explanation: The equation demonstrates that a small amount of mass can be converted into a tremendous amount of energy, as the speed of light squared is an extremely large number.
Details: This calculation is crucial for understanding nuclear reactions, astrophysics, and the fundamental nature of matter and energy in the universe. It forms the basis for nuclear power and atomic weapons.
Tips: Enter mass in kilograms and the speed of light in meters per second. The speed of light is pre-filled with its standard value (299,792,458 m/s) but can be modified if needed for theoretical calculations.
Q1: Why is the speed of light squared in the equation?
A: The speed of light squared (c²) acts as the conversion factor between mass and energy, representing the enormous amount of energy contained within mass.
Q2: What are practical applications of this equation?
A: Nuclear power generation, nuclear weapons, understanding stellar processes, and particle physics research all rely on this fundamental principle.
Q3: Can we convert energy back to mass?
A: Yes, this occurs in particle accelerators where high-energy collisions can create new particles with mass from energy.
Q4: Why is the energy output so large for small masses?
A: Because the speed of light is extremely large (299,792,458 m/s), and squaring this number results in an enormous conversion factor (approximately 9 × 10¹⁶).
Q5: Is this equation used in everyday technology?
A: While not directly used in most everyday devices, it underpins nuclear power generation and medical applications like PET scans and radiation therapy.
