Per NCERT, what is INSTANTANEOUS acceleration?
AHalf the average acceleration
BThe limit of average acceleration as Δt → 0: a = dv/dt
CAlways zero
DFinal velocity divided by total time
Answer & Solution
Correct answer: B. The limit of average acceleration as Δt → 0: a = dv/dt
Per NCERT Eq 2.3, a = lim(Δt→0) Δv/Δt = dv/dt. Analogous to instantaneous velocity.
