Inertia is the property of an object to remain at constant velocity unless acted upon by an outside force. The principle of inertia is one of the fundamental principles of classical physics which are used to describe the motion of matter and how it is affected by applied forces. Today, it is most commonly defined using Sir Isaac Newton's First Law of Motion, which states:
“The vis insita, or innate force of matter is a power of resisting, by which every body as much as in it lies, continues in it's present state, whether it be of rest, or of moving uniformly forwards in a right line. ”
The description of inertia presented by Newton's law is still considered the standard for classical physics. However, it has also been refined and expanded over time to reflect developments in understanding of relativity and quantum physics which have led to somewhat different (and more mathematical) interpretations in some of those fields.

Inertia is just a fancy way of saying that an object will stay at a constant speed until an outside force changes it. Like a space ship in space will keep going the same speed if you don't run into anything or step on the gas.

Inertia is the tendency of an object to remain at rest, or keep moving at constant speed in a straight line.

Inertia of a body is the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force, to change the state.

Inertia is what prevents a body from changing direction quicky especially when the body is making a turn at high speed

Inertia is the tendancy for things that are in motion to stay in motion and things that are at rest to stay at rest unless otherwise changed by an outside object or force.

Inertia is RESISTING force a body has. For eg to move an object I have to apply a force larger than its mass, to OVERCOME it so that I could move the object.

get on a bike and hit a brick wall pedeling as fast as possible and you will find out!!... hehe...inertia is when an oblect is traveling and has nothing stopping it aka gravity or friction... it will continue to move... like you hitting the wall and the bike stopping
