Question

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

Answer 1

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 Watt

option (B) momentum, it cannot be not possible because momentum = mass × Velocity . so, its SI unit is Kgm/s or Ns

option (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.

Answer 2

Answer:

Work

Explanation:

In this question,

We need to find the unit of energy is same as

Option (A) power, it cannot be possible because power is energy consumed per unit time. so, its S.I unit is Kgm²/s³ or Watt

Option (B) momentum, it can't be possible because momentum = mass × Velocity. So, its S.I unit is Kgm/s or Ns

Option (C) work, yes it is possible. its S.I unit is Kgm²/s² or Joule.

Option (D) force, it is also not possible. As we know, Newton is S.I unit of force.  

Hence, the unit of energy is the same as the unit of work.
