How does a squid propel itself through water and how does it apply to Newton's Third Law?

Answer 1

a squid has special muscles that suck water in and "jet" it out pushing it forward....

any reaction has an equal and opposit reaction

the squid pushes a mass of water...the water pushes the squid forward.

Answer 2

once you stroll, you bypass forward. it somewhat is Newton's 0.33 regulation at paintings. observe that as quickly as you stroll, what you're truthfully doing is pushing the floor backward such as your feet. Newton's third regulation says that on each occasion a physique A (you) exerts a tension upon a physique B (the Earth), then physique B will exert a tension of equivalent intensity yet opposite direction on physique A (you). It seems hence that the Earth impels you forward with an identical intensity as you attempt to push it backwards. Now, you may ask your self what happens to the Earth once you push it backwards. properly, the intensity of the strain with which you push it lower back is an identical by using fact the intensity of the strain with which it pushes you forward, yet by using fact the Earth has so lots extra mass, that doesn't look to worry it too lots, on an identical time as an identical tension is going a protracted way in direction of moving you on your trip spot.

Answer 3

along with justin's answers many squids have capacity to bind air at the lower end of the arm
when on water this air also helps them to float and the other is what justin said
