# What is the source of inertia?

• fasteddie1371
In summary, Inertia is the resistance of an object to change its state of motion and it is not caused by a specific particle or force. It is a fundamental property of matter. The concept of "inertialessness" is purely science fiction and there is currently no known way to nullify or remove an object's inertia. Even if it were possible, an inertialess object would not be able to go faster than light as the speed of light is the maximum speed at which any object can travel.

Is there a specific particle or force that gives an object inertia? Going back to the 1940's science fiction ideas of "inertialessness", is there a way to nullify or remove an objects inertia? And if so, could an inertialess object go faster than light?

No; inertia is the name for the phenomena that objects with mass resist acceleration.

According to the theory of relativity everything related with energy, momentum, and stress contributes to inertia as well as gravity.

## What is the source of inertia?

The source of inertia is a property of matter that causes objects to resist changes in their state of motion. It is a fundamental concept in physics and is closely related to the concept of mass.

## How does inertia affect objects?

Inertia affects objects by causing them to maintain their current state of motion. This means that an object at rest will remain at rest, and an object in motion will continue moving in the same direction and at the same speed unless acted upon by an external force.

## Is inertia the same as momentum?

No, inertia and momentum are related but not the same. Inertia is a property of matter, while momentum is a measure of an object's motion. Inertia determines how difficult it is to change an object's state of motion, while momentum is a measure of how much motion an object has.

## What factors affect an object's inertia?

The main factor that affects an object's inertia is its mass. Objects with larger mass have greater inertia and are more difficult to accelerate or decelerate. The shape and size of an object can also affect its inertia, as well as external forces acting on the object.

## Can inertia be overcome?

Inertia can be overcome by applying an external force to an object. This force can cause the object to change its state of motion, either by accelerating or decelerating. The amount of force needed to overcome inertia depends on the mass of the object and the magnitude of the desired change in motion.
