Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes its speed or direction to change. It is one of the fundamental principles in classical physics, and described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). [1]
Learn the meaning of inertia, a property of matter that resists change in motion, and see examples, synonyms, and word history. Find out how inertia applies to other physical quantities and phenomena.
Inertia is the property of a body that resists changes in its motion or state of rest. Learn about the two types of inertia (mass and moment of inertia), their applications and examples, and how they relate to physics concepts such as force, torque and weak interaction.

Learn about the law of inertia, also known as Newton's first law of motion, which states that an object will continue to be in the state of rest or in a state of motion unless an external force acts on it. Explore the types of inertia, examples, and Galileo's experiments that proved the law of inertia.
