Per NCERT, can acceleration and velocity change values ABRUPTLY at an instant — in realistic situations?
ANo — physical changes in velocity and acceleration are always CONTINUOUS, never instantaneous
BYes, instantly
COnly in collisions
DOnly if mass is zero
Answer & Solution
Correct answer: A. No — physical changes in velocity and acceleration are always CONTINUOUS, never instantaneous
Per NCERT §2.3 note, real-world v and a vary continuously, not instantaneously.
