SUMMARY
Dimensional analysis is a mathematical technique used to check the consistency of equations and derive relationships between physical quantities. It involves expressing a physical quantity in terms of its fundamental dimensions, such as mass (M), length (L), and time (T). The example provided illustrates the relationship E ~ G, M, R, where the equation [E] = k[G^α * M^β * R^γ] demonstrates how different physical quantities can be related through their dimensions. This method is essential for validating solutions in physics and engineering.
