Questions and Answers

What is inertia primarily the tendency of an object to do?

Accelerate when a force is applied

Remain at the same speed

Resist a change in its motion (correct)

Attract other objects

According to Newton's first law of motion, what will happen to an object at rest?

It will start moving spontaneously.

It will begin to accelerate towards other objects.

It will remain at rest unless acted upon by an unbalanced force. (correct)

It will rotate indefinitely.

Inertia

The tendency of an object to resist a change in motion.

Newton’s First Law of Motion

An object at rest stays at rest; an object in motion stays in motion unless acted upon by an unbalanced force.

Unbalanced Force

A force that causes a change in the motion of an object.

Law of Inertia

Another name for Newton's first law, emphasizing inertia's role in motion.

Study Notes

Inertia

Inertia is the resistance of an object to changing its motion.
All objects possess inertia, regardless of whether they are still or moving.
Inertia explains Newton's First Law of Motion.
Newton's First Law states that a stationary object stays still, and a moving object keeps moving at a constant velocity unless acted upon by an unbalanced force.
Newton's First Law is also known as the law of inertia.

Description

Explore the concept of inertia, the resistance of an object to changes in its motion. Understand how this principle relates to Newton's First Law of Motion, which states that objects remain at rest or in uniform motion unless influenced by an unbalanced force. Test your knowledge on the key principles of motion.
