how does newtons third law apply to a fish swimming through water
a fish pushes water backwards with its fins is the action. the water pushing the fish is the reaction
the water pushes against the fish's body
the fish swallows water when the fish spits out the water the force of the water moves the fish
the fish's fins wiggle to create a force that propels the fish forward
Newton's third law states that for every action, there is an equal and opposite reaction. In the context of a fish swimming through water, this law applies in the following ways:
1. When a fish pushes water backwards with its fins (action), the water exerts an equal and opposite force on the fish's body (reaction). This force helps propel the fish forward in the water.
2. As the water pushes against the fish's body, the fish experiences a reaction force that aids in its motion through the water.
3. When a fish swallows water and then spits it out, the force exerted by the exiting water creates a reaction force that can move the fish in the opposite direction.
4. The wiggling motion of the fish's fins creates a force that propels the fish forward. According to Newton's third law, as the fins push against the water (action), the water pushes back with an equal and opposite force (reaction), moving the fish forward.
