What is the law of inertia?
Inertia, property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity. It is a passive property and does not enable a body to do anything except oppose such active agents as forces and torques.

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]
An object’s inertia determines what happens when a force is applied to it. Something with a lot of inertia, like a heavy, fast moving object, will resist changing its motion.
Jul 1, 2023 · In physics, the concept of inertia refers to the resistance of an object to any change in its velocity, which includes changes to both speed and direction. It’s a fundamental principle that underlies the motion of objects.
Inertia is the tendency for an object at rest to remain at rest, or for a moving object to remain in motion in a straight line with constant speed. This key property of objects was first described by Galileo.
Jul 22, 2024 · Law of inertia, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This law is also the first of Isaac Newton’s three laws of motion.
Feb 20, 2022 · Define mass and inertia. Understand Newton's first law of motion. Experience suggests that an object at rest will remain at rest if left alone, and that an object in motion tends to slow down and stop unless some effort is made to keep it moving.
