For many reasons. The simplest one is: [mass] times [speed] does not have
the dimensions of [energy], but [mass] times [speed squared] has.
E = energy e=mc2 (or Engergy (e) equals Mass (m) times the Velocity of Light (c) squared {the speed of light times itself}).
Electrical energy is the ability of an electrical system to do work. It is measured in joules and is equal to the product of power (in watts) and time (in seconds). In mathematical terms, electrical energy equals power multiplied by time.
The speed of light in a vacuum is represented by the symbol 'c' and is approximately 299,792 kilometers per second (or about 186,282 miles per second). It is a fundamental constant in physics and plays a crucial role in many scientific equations and theories.
299,792,458 metres per second, which is roughly 186,000 miles per second.Since that's a bit of a mouthful, the figure is commonly known as c, as in E=mc2.
E=MC2 is the formula for the amount of energy (E) derived from a certain mass (M) times the speed of light squared (C2). The speed of light is a huge number, and multiplying it by itself results in an unimaginably higher number. Hence, the energy resulting from the formula is likewise huge.
No. E=mc2 is a formula. Energy equals mass times the speed of light squared.
E (Energy) equals M (Mass) times C2 (speed of light square)
speed of light
Speed of light.
C = Speed of light, C2 =speed of light squared
plz answer :(
The quantity designated by the letter "c" is the speed of light
c = the speed of light.
c is the speed of light in vacuum.
The speed of light in vacuum.
The letter 'c' in that equation represents the speed of light.
Energy equals mass multiplied by the speed of light squared
