Chapter 2: Motion in a Straight Line - Assertion-Reason Quiz

Assertion (A): The numerical limiting method for finding instantaneous velocity gives an approximate value, while the calculus method gives the exact value. Reason (R): The numerical method computes Δx/Δt for small but finite Δt, which only approaches (never exactly equals) the limit; calculus evaluates dx/dt analytically and gives the exact limiting value.
