Per NCERT, how does a CANOE move forward when the canoeist pushes water with a paddle?
AThe wind blows the canoe forward
BGravity pulls the canoe forward
CThe paddle's weight pushes the canoe
DThe paddle pushes water BACKWARD; water pushes paddle (and canoe) FORWARD — Newton's Third Law
Answer & Solution
Correct answer: D. The paddle pushes water BACKWARD; water pushes paddle (and canoe) FORWARD — Newton's Third Law
Per NCERT §6.6, canoe motion = action (paddle pushes water back) + reaction (water pushes paddle/canoe forward). The other options misstate.
