Understanding the Concepts

* Work: Work is done when a force causes an object to move a certain distance. It's calculated as the product of force and displacement:

* Work (W) = Force (F) × Distance (d)

* Force of Gravity: When lifting an object vertically, you're working against the force of gravity. The force of gravity on an object is its weight, which is calculated as:

* Weight (W) = Mass (m) × Acceleration due to gravity (g)

Calculations

1. Calculate the weight of the mass:

* Weight (W) = 1 N (given)

2. Calculate the work done:

* Work (W) = Force (F) × Distance (d)

* Work (W) = 1 N × 1 m

* Work (W) = 1 Joule (J)

Answer: 1 Joule of work is done when a 1N mass is raised a vertical distance of 1 m.
