Force

Force is a mechanical quantity that changes or tends to change the motion or shape of a body. It is represented mathematically as a vector and has a point of application.

Direct methods involve a direct comparison with a known gravitational force, while indirect methods involve measuring other quantities and calculating force indirectly.

Force can be measured using direct methods by comparing it with the gravitational force on a standard mass, such as by using a balance.
