Inertia is a property of matter that refers to its resistance to changes in motion. It is the tendency of an object to remain at rest or to keep moving with a constant velocity unless acted upon by an external force.
According to Newton's first law of motion, an object will stay at rest or continue moving in a straight line at a constant speed unless acted upon by a net external force. Inertia is the reason why we feel a force pushing us backward when a moving vehicle suddenly stops or why we lurch forward when it starts suddenly.
The inertia of an object depends on its mass. The greater the mass, the greater the inertia. This means that objects with larger masses require more force to change their motion compared to objects with smaller masses.
Inertia also plays a role in rotational motion. Objects with a larger moment of inertia require more torque to change their rotational state compared to objects with a smaller moment of inertia.
In summary, inertia is the property of matter that describes its resistance to changes in motion. It is a fundamental concept in physics and is responsible for the behavior of objects at rest or in motion.
