Question:

The Unit of Work done is Joule. 1 Joule = ______?

Options:

1 Joule = 1 Newton × 1 Metre

1 Joule = 1 Kilogram × 1 Metre

1 Joule = 1 Newton × 1 Kilogram

1 Joule = 1 Newton × 1 Second

Correct Answer:

1 Joule = 1 Newton × 1 Metre

Explanation:

The correct answer is Option (1) → 1 Joule = 1 Newton × 1 Metre

The correct answer is 1 Joule = 1 Newton × 1 Metre.

Explanation:

In physics, Work ($W$) is defined as the product of the force applied to an object and the displacement caused by that force in the direction of the force.

The formula for work is:

$W = F \times s$

Where:

  • $W$ is Work done (measured in Joules, $J$)
  • $F$ is Force (measured in Newtons, $N$)
  • $s$ is Displacement (measured in metres, $m$)

By substituting the units into the formula:

$1 \text{ Joule} = 1 \text{ Newton} \times 1 \text{ metre}$
