Question

The instantaneous velocity of a particle at a specific moment in time is defined as the
Options
A limit of the average velocity as the time interval approaches zero.
Correct Answer
B total displacement divided by the total time.
C slope of a line connecting two distant points on a position-time graph.
D area under the velocity-time graph up to that moment.
Correct Answer

Option A is the correct answer.

Detailed Explanation

Instantaneous velocity is the velocity at a single instant. It is mathematically defined as the limit of the average velocity as the time interval Δt over which it is measured approaches zero (v = lim_{Δt→0} Δx/Δt = dx/dt).

Hint

Think about what a speedometer reads at a precise instant—it's not an average over a long period.
