E = m*c2
E is energy.
m is mass.
c is the speed of light.
The quantity designated by the letter "c" is the speed of light
The letter 'c' in that equation represents the speed of light.
'c' represents the speed of light.
speed of light
E is a multiple of the speed of light, c is the speed of light, m is merely a mass.
Speed of Light is represented by c. It is a constant, and is equal to 299,792,458 meters per second.
The quantity designated by the letter "c" is the speed of light
The letter 'c' in that equation represents the speed of light.
'c' represents the speed of light.
The equation E=mc^2 calculates the energy (E) associated with a mass (m) being converted into energy, where c represents the speed of light.
E=mc2 means energy=mass multiplied by the speed of light squared.
C represents a constant (the speed of light).
The quantity that is most likely to be the smallest in the equation E=mc^2 is the mass (m). Mass is typically much smaller than the speed of light squared (c^2), and energy (E) can be significant due to the speed of light's large value.
Energy is a product of 1 scalar quantity which is mass and 1 vector quantity which is the velocity of light within a vacuum. The velocity of light in the equation is squared which returns an absolute value negating any sign it has. This results in both terms having no sign. A vector quantity must have both a direction and a magnitude. The product returned will always be a positive quantity which means it has no direction.
A light year is a unit of distance, not a physical quantity. It represents the distance that light travels in one year in a vacuum.
The light power equation, also known as the radiant flux equation, is P E/t, where P represents power, E represents energy, and t represents time. This equation is used in physics to calculate the amount of energy transferred by light per unit of time. It helps in understanding the intensity of light and its impact on various phenomena, such as heating, illumination, and photochemical reactions.
The m is for mass and c is for the speed of light. The attached link is Albert Einstein explaining the theory of relativity. It has subtitles as his accent is very thick.
