Questions and Answers

What is the Law of Inertia?

The tendency of an object to remain at rest unless acted upon by an outside force and the tendency of an object to remain in constant motion unless acted upon by an outside force. (correct)

The tendency of an object to remain at rest unless acted upon by an outside force only.

The tendency of an object to remain in motion unless acted upon by an outside force only.

The tendency of an object to remain in constant motion unless acted upon by an inside force.

How is the measure of the amount of matter in an object defined?

Volume

Density

Weight

Mass (correct)

What is the relationship between mass and inertia?

No relationship between mass and inertia

Directly Proportional (Increased mass means increased inertia; lower mass means lower inertia) (correct)

Mass and inertia are unrelated concepts

Inversely Proportional (Increased mass means decreased inertia; lower mass means increased inertia)

Study Notes

Inertia and Mass

The Law of Inertia states that an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
The measure of the amount of matter in an object is defined as its mass.
Mass is a measure of an object's inertia, with more massive objects having a greater tendency to resist changes in their motion.

Force and Inertia

According to the Law of Inertia, an external force is required to change the motion of an object.
The role of force is to overcome an object's inertia, either to cause it to accelerate, decelerate, or change direction.
The more massive an object, the greater the force required to change its motion.

Key Points

Inertia is the tendency of an object to resist changes in its motion.
The Law of Inertia applies to both objects at rest and objects in motion.
