Weight FAQs:

Q: Is weight a vector whose magnitude , often denoted by an italic letter W, is the product of the mass m of the object and the magnitude of the local gravitational acceleration g?

A: Yes, thus: W = mg.

Q: Is weight that of force?

A: Yes, and which in the International System of Units is the newton.

Q: Was weight given by Euclid?

A: Yes, and who defined weight as: "weight is the heaviness or lightness of one thing, compared to another, as measured by a balance".

Q: Is weight a force that results from the action of gravity on matter: it measures how strongly the force of gravity pulls on that matter?

A: Yes.

Q: Was weight the direct cause of the falling motion of an object?

A: Yes, and the speed of the falling object was supposed to be directly proportionate to the weight of the object.

Q: Is weight a measure of the magnitude of the reaction force exerted on a body?

A: Yes.

Q: Is weight a term that is generally found in commerce or trade applications?

A: Yes, and refers to the total weight of a product and its packaging.

Q: Is weight used?

A: Yes, and the operational weight measured by an accelerating scale is often also referred to as the apparent weight.

Q: Is weight commonly measured using one of two methods?

A: Yes.

Q: Was weight split into a "still weight" or pondus?

A: Yes, and which remained constant, and the actual gravity or gravitas, which changed as the object fell.

Q: Is weight unimportant for many practical purposes because the strength of gravity does not vary too much on the surface of the Earth?

A: Yes.

Q: Is weight the weight of the packaging alone?

A: Yes.

Q: Are weights calibrated at the factory for standard gravity, the balance will measure standard weight, i.e?

A: Yes, what the object would weigh at standard gravity, not the actual local force of gravity on the object.

Q: Is weight caused by the force exerted by fluids in the vestibular system?

A: Yes, and a three-dimensional set of tubes in the inner ear.

Q: Was weight proportionate to the amount of matter of an object?

A: Yes, and not the speed of motion as supposed by the Aristotelean view of physics.
