Einstein's MassEnergy Equivalence
Einstein's MassEnergy Equivalence, encapsulated in the iconic equation E=mc², stands as one of the most profound concepts in the realm of physics. Let's embark on a journey through the historical context, theoretical underpinnings, and practical implications of this groundbreaking theory.
Introduction Of Einstein's MassEnergy Equivalence
In the vast expanse of physics, few theories have left an indelible mark as Einstein's MassEnergy Equivalence has. This article delves into the intricacies of the equation E=mc², exploring its historical genesis, theoretical foundations, and its farreaching impact on the scientific landscape.
Einstein's Equation: E=mc²
Explanation of the Equation
At its core, the equation signifies the equivalence of energy (E) and mass (m) connected by the speed of light (c) squared. Breaking down each component unveils a profound interplay between matter and energy, challenging traditional notions.
Einstein's MassEnergy Equivalence Formula & Examples
Einstein's MassEnergy Equivalence is expressed by the famous formula: \[ E = mc^2 \] where \(E\) represents energy, \(m\) is mass, and \(c\) is the speed of light.
Formula
The formula \(E=mc^2\) signifies the equivalence of energy and mass, demonstrating the profound relationship between the two in the context of the speed of light.
Examples
Example 1:
Calculate the energy (\(E\)) when the mass (\(m\)) is 2 kg, and the speed of light (\(c\)) is approximately \(3 \times 10^8\) m/s.
\[ E = (2 \, \text{kg}) \times (3 \times 10^8 \, \text{m/s})^2 \]
\[ E = 2 \times (9 \times 10^{16} \, \text{kg} \cdot \text{m}^2/\text{s}^2) = 1.8 \times 10^{17} \, \text{Joules} \]
Example 2:
If the energy (\(E\)) is 5 × \(10^{17}\) Joules, find the equivalent mass (\(m\)) using the formula \(E=mc^2\).
\[ m = \frac{E}{c^2} = \frac{5 \times 10^{17} \, \text{J}}{(3 \times 10^8 \, \text{m/s})^2} \]
\[ m \approx \frac{5 \times 10^{17} \, \text{kg} \cdot \text{m}^2/\text{s}^2}{9 \times 10^{16} \, \text{m}^2/\text{s}^2} \approx 5.56 \, \text{kg} \]
Solution
The formula \(E=mc^2\) not only establishes the relationship between mass and energy but also allows us to calculate one given the other. It has profound implications in physics and is fundamental to our understanding of the universe.
