- inertia
- a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
- length
- the measurement or extent of something from end to end
- mass
- a physical quantity of matter in an object. Mass is measured in terms of the weight of a body.
- moment of inertia
- quantitative measure of the rotational inertia of a body
