How is weight calculated?

m, mass (kg) × a, acceleration (m/s²)

m, mass (kg) × g, acceleration due to gravity (10m/s²)

Weight is defined as the force exerted by gravity on an object and is calculated using the mass of the object and the acceleration due to gravity. The formula for weight is given by the equation:

Weight = mass × acceleration due to gravity

In this equation, mass is measured in kilograms (kg) and the acceleration due to gravity (denoted as g) is typically approximated as 10 m/s² near the Earth's surface. Thus, when you calculate weight using this formula, you obtain a result measured in newtons (N), which is the unit of force.

This option accurately represents the fundamental relationship between mass and gravitational force, making it the correct answer. Other provided choices pertain to different physical concepts that do not appropriately describe the calculation of weight. For instance, options involving force divided by distance or involving kinetic energy are unrelated to the definition or measurement of weight.
