Understanding the Dimensional Formula of Energy
Asked by Sultanah Fatimah · 2 years ago
Can someone explain the dimensional formula of energy in simple terms? I'm preparing for my NEET exam and want to make sure I fully understand this concept.

Sure! The dimensional formula of energy can be derived from its definition. Energy is the capacity to do work, and work is defined as the product of force and displacement. The unit of force is Newton (N), which has the dimensional formula [MLT-2]. Displacement has the dimensional formula [L]. So, the dimensional formula of energy (or work) becomes:
[Energy] = [Force] × [Displacement] = [MLT-2] × [L] = [ML2T-2]
So, the dimensional formula for energy is [ML2T-2]. This formula is crucial for solving many physics problems, especially in mechanics and thermodynamics.
