The unit of energy is same as the unit of(A) power (B) momentum(C) work (D) force |

Answer» : option (C) work explanation : SI unit of energy is kgm²/s² or JOULE. LET's check all the options ! option (A) power , it cannot be possible because power is energy consumed per unit time. so, its SI unit is Kgm²/s³ or Wattoption (B) momentum, it cannot be not possible because momentum = mass × Velocity . so, its SI unit is Kgm/s or Nsoption (C) work, YES it is possible. work is the dot product of force and displacement. so, its SI unit is Kgm²/s² or Joule .option (D) force, it is obviously not possible. as all KNOW , Newton is si unit of force. hence, The unit of energy is same as the unit of work. |
