Why does a 30-kg barbell have more inertia than a 10-kg barbell?

Why does the mass of an object affect its inertia? The greater the weight (or mass) the more inertia. 30 kg has more mass than 10 kg, therefore, it has more inertia.

Understanding Inertia:

Inertia is the resistance of an object to change its state of motion. It is a property that is proportional to the mass of an object. The greater the mass, the greater the inertia. Inertia is a fundamental concept in physics that helps us understand why objects behave the way they do.

Mass and Inertia Relationship:

Mass is a measure of the amount of matter in an object. Objects with more mass have more inertia because they require more force to change their state of motion. In other words, the greater the mass of an object, the more resistance it has to changes in its velocity.

Barbell Example:

When comparing a 30-kg barbell to a 10-kg barbell, the 30-kg barbell has more mass, therefore it has more inertia. This means that the 30-kg barbell would require more force to start moving, stop moving, or change its direction compared to the 10-kg barbell.

So, in summary, the mass of an object directly affects its inertia. A heavier object will have more inertia compared to a lighter object because it has more resistance to changes in its motion.
