The SI unit for gravitational potential energy is ____
|
|
kg∙m∙s^-1
|
|
|
kg∙m∙s^-2
|
|
|
kg∙m^2∙s^-2
|
|
|
kg∙m^-1∙s^-1
|
Explanation:
Detailed explanation-1: -SI unit of work (W) is Joule(J) and mass is kilogram (Kg). Therefore, the SI unit of gravitational potential is JKg=JKg−1 .
Detailed explanation-2: -The unit of gravitation potential is Joule per kilogram.
Detailed explanation-3: -Hence, N m 2 / k g 2 is the SI unit of G i.e Gravitational Constant.
Detailed explanation-4: -Potential Energy : (P.E. or U) “The energy possessed by a bo tody due its position above the ground . or change in state.” UNIT : Unit of P.E. = S.I. UNIT OF ENERGY = Joule (J)
Detailed explanation-5: -The unit of gravitational field intensity is N/kg.
