The Internet has many places to ask questions about anything imaginable and find past answers on almost everything.

## What is the relationship of inertia and mass?

Mass is the quantity or measure of inertia in an object. The more mass found in an object, the more inertia it contains and therefore the greater its tendency to resist change.

## How does mass affect inertia?

This is INERTIA. Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects. The more massive the object (more inertia) the harder it is to start or stop.

## Do objects with less mass have more inertia?

Lighter objects have more inertia than heavy objects. Weight or mass does not affect the amount of inertia of an object. All things have inertia but only when they are at rest. Lighter objects have less inertia than heavy objects.

## Is inertia the same as mass?

Mass is a measure of the amount of matter in an object. Inertia is the resistance of a physical object to any change in its state of motion.

## Which vehicle has higher inertia?

A bus has more inertia, because it has more mass. So, greater force is needed to change the state of the body of greater mass.

## On what factor does inertia of a body depends which has more inertia?

Inertia of abody depends on its mass. a cricket ball has more mass than a rubber ball, hence it has more inertia.

## Is moment of inertia dependent on mass?

The moment of inertia depends not only on the object’s mass, but also the distribution of that mass in relation to the axis of rotation.

## Which factors does the inertia of rest depend on?

Inertia depends on density and mass. Inertia is directly proportional to mass and density of an object. More the mass of an object, more is the inertia of the body.

## What does the inertia of a moving object depend on?

The inertia of a moving object depends on the mass of the object. Heavier the item, the Heavier is its tendency to resist the change in state of motion. Mass is the quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has.

## What cause the object change in motion?

A force can speed up or slow down an object. A force can change the direction in which an object is moving. A bigger force on an object will produce a bigger change in the motion. A heavier object requires a larger force than a lighter object in order to undergo the same change in motion.

## How can you tell that the object is in motion?

An object is in motion when its distance from another object is changing. Whether an object is moving or not depends on your point of view. An object is in motion if it changes position relative to a reference point. You assume that the reference point is stationary, or not moving.

## How can we stop an object from motion?

The force stopping the object’s motion might be an obvious one – the ground! Friction is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance). Even air causes friction.

## What happens when two objects collide at the speed of light?

Originally Answered: What happens when two objects moving at the speed of light collide with each other? Release of infinite energy. Because, the object moving at the speed of light has already gained infinite mass. The momentum and force associated with the movement are also considered to be infinite.

## What is the force needed to stop an object in motion is called?

Galileo and the Concept of Inertia. Galileo reasoned that moving objects eventually stop because of a force called friction.

## Why is it easier to move an object already in motion?

Static friction(the friction which keeps the object at rest) is slightly more than sliding friction.So,it is easier to keep an object moving which is already in motion than to move it from rest.

## Is it harder to get an object moving from rest or keep it moving?

For an object at rest on a flat table, static friction is zero. If you push horizontally with a small force, static friction establishes an equal and opposite force that keeps the book at rest. It is harder to move a stationary object than it is to keep a moving object in motion.
