Question

State the unit of the physical quantity
obtained by the formula (U/g h) where
U is gravitational potential energy and
his height​

Answer 1

The units of physical quantity obtained by the formula (u/gh) is kilogram(kg)

• The unit of the quantity can be obtained by substituting the respective units of known physical quantities in the formula.
• The unit of gravitational potential energy is kg-m²/s², the unit of acceleration due to gravity is m/s² and the units of height is m.
• From the given relation

                   = (kg-m²/s²) / (m/s²)×m

                   = kg

• The unit of the quantitity represented in the above relation is kilogram.
