Question

derive and expression for a potential energy (PE) of a body mass 'm' at height h' with acceleration due to gravity g' using dimensional method​

Answer 1

$\huge\tt\pink{\boxed{\tt{\blue{★\:Answer}}}}$

For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2.
