Example of Mass

Mass is broadly defined as the properties of a body which cause it to have 'weight'. A method of defining mass on Earth is the equation W = mg, meaning that the weight of an object equals its mass multiplied by the force of gravity.

Examples of Mass:

Inertial mass- acceleration in the presence of an applied force

Vertical section drawing of Cavendish's torsion balance instrument including the building in which it was housed. The large balls were hung from a frame so they could be rotated into position next to the small balls by a pulley from outside. Figure 1 of Cavendish's paper.

An apple experiences gravitational fields directed towards every part of the Earth; however, the sum total of these many fields produces a single powerful gravitational field directed towards the Earth's center.
