This article is about the physical concept. For other uses, see

Weight (disambiguation).

A

spring scale measures the weight of an object (according to the operational definition)

This

top-fuel dragster can accelerate from zero to 160 kilometres per hour (99 mph) in 0.86 seconds. This is a horizontal acceleration of 5.3 g. Combined with the vertical g-force in the stationary case the

Pythagorean theorem yields a g-force of 5.4 g. It is this g-force that causes the driver's weight if one uses the operational definition. If one uses the gravitational definition, the driver's weight is unchanged by the motion of the car.
In science and engineering, the weight of an object is the Its magnitude (a thus: W = mg. When considered a

vector, weight is often denoted by a bold letter W. The

unit of measurement for weight is that of force, which in the

International System of Units (SI) is the

newton. For example, an object with a mass of one kilogram has a weight of ...
