Questions and Answers

What does inertia primarily determine about an object?

The direction of its motion
Its tendency to resist changes in motion (correct)
The distance it can travel
The speed at which it can rotate

According to Newton's first law, when will an object change its state of motion?

Only if it is moving in a circle
In the presence of external or unbalanced forces (correct)
When it gains speed
When it is subjected to friction

How does mass affect an object's inertia?

Inertia is only influenced by surface area
Mass does not affect inertia at all
More mass means less inertia
More mass increases inertia (correct)

Study Notes

Measure of Inertia

Objects resist changes in their state of motion due to inertia.
Inertia is directly related to mass; more massive objects have greater inertia.
More inertia means it is harder to move, slow down, speed up, or change direction of an object.

Newton's First Law

An object at rest remains at rest, and an object in motion continues in motion unless acted upon by an external net force.
The principle emphasizes the role of unbalanced forces in changing an object's state of motion.

Law of Inertia

A body remains at rest or moves at constant velocity in the absence of an external unbalanced force.
Highlights the predictable behavior of objects when no net force is applied.
