An octopus propels itself through the water by injecting water through a funnel in its by. How does this demonstrate newtons third law?

Answer 1

Newton's third law states that for every action, there is an equal and opposite reaction. In the case of an octopus, when it injects water through the funnel, it creates an action force. The water, in turn, produces an equal and opposite reaction force, which propels the octopus forward. This demonstrates Newton's third law because the force applied by the octopus (action) is met with an equal and opposite force (reaction) that propels the octopus through the water.
