How does E=MC^2 convert to Joules? How can the speed of light measured in m/s and mass measured in grams convert to joules?
E=MC^2 is an equation that represents the relationship between energy (E), mass (M), and the speed of light (C). It states that energy and mass are equivalent and can be converted into one another.
The equation E=MC^2 can be used to convert between mass and energy, with the units of Joules (J) being the unit for energy. To convert mass into energy in Joules, you would multiply the mass (in kilograms) by the speed of light squared (299,792,458 meters per second)^2.
The speed of light squared is included in the equation to account for the relationship between mass and energy. The speed of light is a constant and a very large number, so squaring it allows for a more significant conversion between mass and energy.
The equation E=MC^2 can be used to convert between any units of mass and energy, as long as the units are consistent. For example, if mass is given in kilograms, then energy should be in Joules.
No, E=MC^2 is not the only equation that can be used to convert between mass and energy. Other equations, such as the energy-momentum relation E^2=(pc)^2+(Mc^2)^2, can also be used for this conversion depending on the specific scenario. However, E=MC^2 is the most well-known and widely used equation for this purpose.
