Detailed explanation-1: -Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for “the principle of inertia” as described by Newton in his first law of motion.
Detailed explanation-2: -Definition of Inertia: The inherent property of an object due to which it resists any change in its state of rest or of uniform motion in a straight line by itself is called inertia.
Detailed explanation-3: -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. Inertia is a passive property and does not enable a body to do anything except oppose such active agents as forces and torques.
