Which physical quantity has dimensions [MLT-2]?

The physical quantity with dimensions [MLT⁻²] is force. In the International System of Units (SI), force is measured in newtons (N), and its dimensions are mass (M) times length (L) divided by time squared (T⁻²). This can be represented by the formula:-

Force (F) = Mass (M) x Acceleration (a)

In this formula, acceleration has dimensions of length divided by time squared [LT⁻²], which matches the dimensions of force.
