Weight is the force exerted by gravity on an object. It is the product of the mass of the object and the acceleration due to gravity. The formula for calculating weight (\( W \)) is given by:
\[
W = m \cdot g
\]
where:
- \( W \) is the weight,
- \( m \) is the mass of the object, and
- \( g \) is the acceleration due to gravity.
On the surface of the Earth, the average value of \( g \) is approximately \( 9.81 \, \text{m/s}^2 \). Therefore, an object with a mass of 1 kilogram would weigh about 9.81 newtons (N) due to Earth's gravitational pull. Weight is a vector quantity, which means it has both magnitude and direction (toward the center of the Earth).
