Question

The dimensional formula of kinetic energy is

• A. Young's modulus of elasticity
• B. Stress
• C. Strain
• D. Pressure

Answer 1

The correct option is D Pressure

Kinetic energy = $\frac{1}{2}m{v}^2$

Mass = $\left[M\right]$, Velocity = $\left[\frac{L}{T}\right]$ , $velocit{y}^2$ = $\left[\frac{L^2}{T^2}\right]$

Dimensional formula for kinetic energy = $\left[M{L}^2{T}^{-2}\right]$
