NEET Physics Speed & Velocity Assertion Reason Question
Assertion (A): Instantaneous speed is always equal to the magnitude of instantaneous velocity.
Reason (R): Instantaneous velocity is defined as the limit of average velocity as the time interval approaches zero.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The assertion is true as instantaneous speed is defined as the magnitude of instantaneous velocity. The reason correctly explains this because instantaneous velocity is the limit of average velocity as time interval approaches zero, aligning with how instantaneous speed is derived.
