Answer:
To find:
SI unit of work done.
Derivation:
Work done is the amount of energy used to accelerate a body over a certain distance.
Mathematically , we can say that :
Work Done = Force × Displacement
=> W = F × D
=> W = ( M × acc.) × D
Now, we can get the SI unit of work done by taking all the SI unit of the components on the RHS.
SI unit of
- Mass => Kg
- Acceleration => metre/sec²
- Displacement => metre
So SI unit of Work done is
Kg × (metre/sec²) × metre
=> Kg metre²/sec²
This unit is called the "Joule" as a whole.
Final answer is (Joule) or Kg metre²/sec²
