Per NCERT Class 11 Physics Ch 2, what is INSTANTANEOUS VELOCITY of an object at an instant t?
ATotal displacement divided by total time
BAlways the same as average velocity
CAverage of starting and ending velocities
DThe limit of the average velocity as the time interval Δt → 0; equivalent to dx/dt at that instant
Answer & Solution
Correct answer: D. The limit of the average velocity as the time interval Δt → 0; equivalent to dx/dt at that instant
Per NCERT Eq 2.1, v = lim(Δt→0) Δx/Δt = dx/dt. The other options describe other quantities.
