Question

Assertion and reason are given in following question. Each question have four options. One of them is correct select it. (A) Assertion is true. Reason is true and reason is correct explanation for Assertion. (B) Assertion is true. Reason is true but reason is not the correct explanation of assertion. (C) Assertion is true. Reason is false. (D) Assertion is false. Reason is true. Assertion: It is difficult to move bike with its breaks on. Reason: Rolling friction is converted into sliding friction, which is comparatively larger. (A) a (B) $\mathrm{b}$ (C) $\mathrm{c}$ (D) $\mathrm{d}$

Key Concepts

Assertion vs Reason Format

This format is used in examination questions to assess the ability to relate two statements—the assertion and the reason—and determine whether both are true, and if the reason is a correct explanation of the assertion. It tests analytical thinking, understanding of the subject matter, and the ability to critically evaluate logical relationships between statements.

Types of Friction

Friction is the resistive force that opposes the relative motion between two surfaces. Key types include rolling friction, which occurs when an object rolls over a surface and is typically lower, and sliding friction, which occurs when two surfaces slide against each other and is generally higher. Understanding these differences is essential in analyzing how forces act in various mechanical contexts.
