What is the equation for calculating weight?

The correct equation for calculating weight is derived from the relationship between mass and gravity. Weight is defined as the force exerted by gravity on an object, which is directly proportional to its mass. The formula is expressed as W = (Mass)(Gravity), where "W" represents weight, "Mass" is the amount of matter in the object, and "Gravity" is the acceleration due to gravity, typically approximated as 9.81 m/s² on the surface of the Earth.

The other choices provided relate to different physical concepts. For instance, density and volume are connected, but they do not define weight. Density, which is mass per unit volume, combined with volume gives mass, not weight directly. Similarly, force and area relate to different principles, such as pressure, rather than weight itself. Thus, the understanding of weight as a product of mass and gravitational acceleration is fundamental in the context of physics and rigging in the theatre environment.
