# Which has greater inertia a large mass or a small mass?

A large mass.

The traditional view is to refer to inertia in terms of Newton's First Law of Motion.

However, it became common for Physicists to use the mathematically more useful Newton's 2nd Law of Motion to describe inertia in terms of how difficult it is to change the momentum of a body. The 2nd Law of Motion tells us that Force = Mass x Acceleration. "Inertia" in this context is thus directly proportional to the body's mass.

### What is the relationship between mass and inertia of an object?

The inertia of a body can be defined as the relunctance of a body to acceleration. The mass of a body can be defined as a measure of the inertia of a body. This is because acceleration = resultant force / mass. So, if mass is greater, the less will be the acceleration of the body and hence the greater the inertia.

### If an object has greater speed does it necessarily have a greater inertia?

An object's inertia is its resistance to changes in its motion and mass is the quantitative measure of inertia. Strictly speaking the object's inertia will become larger the faster it goes. But at typical speeds it is unmeasurable or barely measurable . Only when the object's speed is near the speed of light is there a large change in its inertia.

### What will make an object accelerate faster one with less inertia or more momentum?

If an object has more momentum, it has either a greater mass or a greater velocity. If an object has less inertia, it has less mass. So am object with less inertia will accelerate faster than one with greater momentum because of a greater mass, assuming the same force of acceleration is applied to both. However, if the greater momentum is due to greater velocity, not enough information has been provided to answer the question.

### How does mass affect inertia of an object?

The larger the mass, the more inertia it has and vice versa If an object has a large mass it increases to object's tendency to resist movement from an outside force, therefore a larger object has more inertia If an object has a small mass, the mass decreases the object's tendency to resist movement from an outside force, therefore a smaller object has less inertia larger object=harder to move smaller object=eaiser to move

### Why does a semi truck have more inertia?

Inertia is a measure of how resistant an object's motion is to changing that motion, and is related to the mass of an object. Increase mass and inertia increases; decrease mass and inertia decreases. For an object to have greater inertia, it must therefore have greater mass. Semi- trucks are very massive vehicles, much more than others normally found, so they will have more inertia than anything else driven on roads. An average car or…

### Why is moment of inertia of a solid disc smaller than that of a ring?

Moment of inertia depends upon the distribution of mass with respect to the axis of rotation.The greater the distance between the bulk of an object's mass and the axis of rotation, the greater the moment of inertia will be. A solid disk has its mass distributed evenly across its diameter, while a ring has its mass concentrated furthest from the centre of rotation.

### Which describes how the same force affects a small mass and a large mass?

Gravitationally, the same force does not affect a small mass and a large mass. The small mass is acted upon by a smaller gravitational force, and the large mass is acted upon by a larger gravitational force. The result is that the small mass and the large mass fall with the same acceleration, and meet the ground with the same speed. During the fall, onlookers typically nudge each other and remark to each other: "My…

### What is the relationship between interia and mass in 7th grade level?

Inertia is the resistance to a change in motion. Most likely you've felt this in a car when it speeds up quickly and it feels like you're sinking into the seat back. Or, when the car brakes hard and your body moves forward. The relationship between inertia and mass is that the greater the mass, the greater the inertia.
