Question

In a football and stone of same size, the inertia ofa)Football is greater.b)Stone is greater.c)Both the objects is equal.d)None of the above.Correct answer is option 'B'. Can you explain this answer?

Answer

Inertia of stone is greater than the inertia of football because mass of stone is higher than the mass of football even both are of same size.

Answer

Inertia of stone is greater because mass of stone is greater than football...

Answer

Inertia of a Football and Stone

Inertia is the property of an object that describes its resistance to changes in motion. It is directly related to the mass of the object. The greater the mass, the greater the inertia. In this case, we are comparing the inertia of a football and a stone of the same size. Let's analyze why the correct answer is option 'B'.

The Concept of Inertia

In order to understand why the inertia of the stone is greater than that of the football, we need to understand the concept of inertia. Inertia is a fundamental property of matter described by Newton's first law of motion. It states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and direction, unless acted upon by an external force.

Mass and Inertia

Mass is a measure of the amount of matter in an object. It is a scalar quantity and is measured in kilograms (kg). Inertia depends directly on mass. The greater the mass of an object, the greater its inertia. This means that objects with greater mass require more force to change their state of motion.

Comparing the Football and Stone

When comparing the inertia of a football and a stone of the same size, we need to consider their masses. Although the size of the objects is the same, the mass can be different. The stone is likely to have a greater mass than the football due to differences in density and composition.

Explanation for Option 'B'

Option 'B' states that the inertia of the stone is greater than that of the football. This is the correct answer because of the following reasons:

1. Mass: As mentioned earlier, inertia depends directly on mass. Since the stone is likely to have a greater mass than the football, it will also have greater inertia.

2. Density and Composition: Stones are generally denser and more compact than footballs, which are filled with air. This higher density contributes to a greater mass, resulting in greater inertia.

3. Resistance to Change in Motion: Due to its greater inertia, the stone will be more resistant to changes in its motion compared to the football. This means that more force will be required to accelerate, decelerate, or change the direction of the stone compared to the football.

In conclusion, the correct answer is option 'B' - the inertia of the stone is greater than that of the football. This is because the stone has a greater mass, which directly affects its inertia.

Answer

Stone because it has more mass than a football.
