Question

Name a physical quantity which has same unit as of work ?

Answer 1

Explanation :

1. Unit of work is joule (J).
2. The other physical quantity that has the same unit is energy i.e., Joule (J)
3. Work: Work is the product of the component of the force in the direction of the displacement and the magnitude of this displacement.
4. Mathematically, W = (F cos θ) d = F. d

Where,

• W is the work done by the force.
• F is the force, d is the displacement caused by the force
• θ is the angle between the force vector and the displacement vector.

5. The SI unit of work is the joule (J)

6. Energy: Energy is the capacity of a physical system to perform work. Energy can be converted in various forms but not created or destroyed. The various forms of energy are solar, wind, hydro, nuclear, thermal, sound, chemical etc.

7. SI unit of energy is joule (J)
