The Law of Inertia (Newton's First Law of Motion) states that:

• Any object with mass also has inertia

• For every action force, there is an equal and opposite reaction force

• Objects will remain in their current state unless acted on by a net external force

• The acceleration of an object is directly proportional to the net force acting on the object

Inertia can be measured directly.

• True

• False

The Standard Unit (SI) of Measure for Inertia is

• m/s²

• Newtons

• kg

• There is no Standard Unit of Measure for Inertia

The concept of Mass was "invented" by physicists as a measure of Inertia.

• True

• False

A zero net force means that all of the forces acting on a system or object are

• balanced

• unbalanced

• neither balanced nor unbalanced

• balanced and unbalanced

Any combination of Unbalanced Contact or Field (non-contact) Forces on a system or object will result in __________________________.

• inertia

• acceleration

• momentum

• total protonic reversal

The more Mass an object has, the more Inertia it has.

• True

• False

As it relates to Newton's Second Law of Motion, a Net Force on an object of a given Mass results in a certain ______________________ of the object.

• acceleration

• inertia

• momentum

• distance

The formula for Newton's Third Law of Motion is ____________________.

• Force x Mass / Distance

• Force / Mass

• Inertia / Force

• There is no formula for measuring Newton's Third Law of Motion
