What is the weight of a 1-kilogram brick resting on a table?

The weight of an object is determined by the force of gravity acting on it. Weight can be calculated using the formula:

[ \text{Weight} = \text{mass} \times \text{acceleration due to gravity} ]

In this case, the mass of the brick is 1 kilogram, and the standard acceleration due to gravity on the surface of the Earth is approximately 9.81 meters per second squared. For simplicity, this value is often rounded to 10 m/s² in introductory physics problems.

Using the formula:

[ \text{Weight} = 1 , \text{kg} \times 10 , \text{m/s}^2 = 10 , \text{N} ]

This calculation shows that the weight of the 1-kilogram brick is 10 Newtons. Understanding this relationship is fundamental in physics, as it highlights how mass and gravity interact to produce weight, a concept crucial to various applications in science and engineering.
