What is inertial motion?
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 defined as a property of matter by which it remains at the state of rest or in uniform motion in the same straight line unless acted upon by some external force.

- According to the law of inertia, An object will continue to be in the state of rest or in a state of motion unless an external force acts on it.
- Law of inertia is also known as Newton’s first law of motion.
- The tendency of moving back when the stationary bus starts to move. Moving forward when a sudden brake is applied.
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]
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.
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.
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.
Relative Inertia and Collisions; Inertial Mass: Definition and Properties; In everyday language, we speak of something or someone “having a large inertia” to mean, essentially, that they are very difficult to set in motion.
