Weight is measured in pound-force (lbf) or newtons (N). Weight is the __________ an object is pulled by gravity.

Weight is a measure of the force exerted on an object due to gravity. When we refer to weight, we are specifically discussing the gravitational force acting on that object, which is why it is quantified in units such as pound-force or newtons.

In physics, weight is fundamentally a force: it results from the mass of the object multiplied by the acceleration due to gravity. This relationship highlights that weight varies with changes in gravitational force, such as when an object is on different planets or in various gravitational fields.

The other options—load, strength, and pressure—do not correctly define weight. Load can refer to the amount of weight supported by a structure but does not encapsulate the concept of gravitational pull. Strength pertains to the capacity of a material to withstand an applied force without failure, while pressure defines the force applied perpendicular to the surface area of an object, which is a different concept altogether and not directly tied to the gravitational force on an object. Thus, the proper term to describe weight in the context of how an object is influenced by gravity is indeed force.
