Physics · JEE | MOTION IN A STRAIGHT LINE
हिन्दीGiven below are two statements: Statement I: Instantaneous speed at an instant is equal to the magnitude of the instantaneous velocity at that instant. Statement II: The sign of acceleration alone determines whether a particle's speed is increasing or decreasing, independent of the direction of velocity.
View Answer & Solution
Correct answer · Option C
Statement I is correct but Statement II is incorrect.
Explanation
Statement I is correct. Statement II is false because speed increases if acceleration is in the direction of velocity and decreases if opposite, depending on coordinate choice.
