In physics, energy E carries dimensions of mass times length squared, divided by time squared. Use dimensional
analysis to derive a relationship for energy in terms of mass m and speed v, up to a constant of proportionality. Set
the speed equal to c, the speed of light, and the constant of proportionality equal to 1 to get the most famous equation
in physics.

Energy: kg m²s⁻²
Mass = kg
velocity = m/s

E = kmv²; putting k = 1, v = c

E = mc²
