Let's talk about kayaking video.

The physical principles of kayaking in the topic include fluid mechanics and basic mechanics. What we want to examine here is basic mechanics, that is, Newton's law.

According to Newton's third law, when a person paddles backwards, he exerts force backwards, and the reaction of water to people is forward, which is the same. Therefore, canoeing is subjected to the forward force of water on canoeing.

According to Newton's first law, force is the cause of the change of object's motion state, and combined with Newton's second law, force is the cause of acceleration, so kayaking produces forward acceleration.

If you want to keep it simple, write Niu San, Niu Yi and Niu Er as supplements.
