Mass

Mass

Mass is a measure of the inertia of an object.

The more mass an object has, the greater the force needed to give it a particular acceleration.
It is harder to start it moving from rest, or to stop it when it is moving, or to change its velocity sideways out of a straight-line path.

In S.I units, the unit of mass is the kilogram (kg) .
