Inertia can be defined in three ways:
  • the apparent resistance to force
  • the resistance of an object to a change in its motion (or lack thereof)
  • the tendency of an object at rest to stay at rest, and for an object in motion to remain in motion.

These are all really saying the same thing. An object with mass requires force
to change its motion, or to start moving from a stationary position. Once the
force is applied, the object will move at a constant velocity until affected by
another force. Inertia is proportional to the mass of any object - the greater
the mass, the greater its inertia.

Two Examples
The inertia of an object resists a change in its motion. That is why seat belts
are used in cars. When the car turns, your body is still trying to continue in
the original direction. If the car suddenly stops, your body still wants to
continue forward.
Inertia also tries to keep a stationary object stationary. If you have to push a
broken-down car from the road, there is a tendency to resist this movement.
And a heavier car is harder to push than a lighter car, even with the same
tires.
Inertia is the tendency of an object at rest to remain at rest until some force
acts to move it; also, the tendency of a moving object to continue moving
until something acts to stop it.

Inertia is the property of all matter by which it remains in constant, uniform
motion until acted upon by an external force.
Inertia is a measure of mass.

What is moment of inertia?

A2 Moment of inertia is the term used to measure or quantify the amount of mass located at an object's extremities. For example if all the mass of an object was located in a small compact size (like a lead ball) its moment of inertia would be small compared to the same amount of mass shaped into a ( Full Answer )

What does inertia mean?

Inertia means: the tendency of a body to maintain its state of rest or uniform motion unless acted upon by an external force. Inertia means the tendency of an object to resist a change in motion unless an outside force acts on the object

There is no "A inertia." Its just inertia and inertia is the measure of an objects to stay at rest or to keep moving.

Examples of inertia?

if you are in a car, moving at 100km/h you are also moving at 100km/h and lets say the driver suddenly applies the brake,you will slide forward and then slam back into the seat.....right?.......this because the car stops but you continue moving.......how?........because the brakes are applied to the ( Full Answer )

How does inertia work?

It is exactly the same as momentum and covered by Newton's first law of motion.

Inertia measures an object's tendency to remain at rest or keep moving with constant velocity. Inertia depends on the direction of the object. Hope this helped! :D

What is inertia related to?

Inertia is a body's resistance to moving, or to change velocity once under motion. It is a function of mass and velocity. . Inertia can also be described as a body's tendancy to maintain momentum - once it has a specific momentum, it will maintain that same momentum until an outside force acts up ( Full Answer )

What is rotational inertia?

Rotational inertia is sometimes called spin. It involves the movement of a mass around an axis. This moving mass will have some measure of kinetic energy that is due to the fact that it is spinning.

What is an inertia?

inertia is force of matter. It's the force to go forward. For example, earth rotates around the sun. with out inertia, earth would not go around the sun.

Inertia is the tendency of an object to resist a change in motion. It depends upon the objects mass. If an object has more mass, it is more difficult to get it moving. Once it is moving, it is harder to slow it down.

Inertia is the tendency to not want to change, or in simple words, to keep doing what you're already doing.
