Per NCERT Pause and Ponder (§6.4), which of the following situations is POSSIBLE for an object with NO net force acting on it?
AObject remains at rest if at rest, OR keeps moving with constant velocity if already moving
BObject moves with constant acceleration
CObject reverses direction spontaneously
DObject disappears
Answer & Solution
Correct answer: A. Object remains at rest if at rest, OR keeps moving with constant velocity if already moving
Per NCERT, no net force allows (i) at-rest state or (ii) constant-velocity motion. Constant acceleration requires a net force.
