<u>Answer</u>:
Force is directly proportional to the acceleration.
<u>Explanation</u>:
Using to the Newton's second law of motion, we can describe the relationship of force and acceleration.
F = ma
Hence they are directly proportional to each other. If we increase the force in an object then the acceleration of the object will also increase by same. or we can say force is similar to acceleration. Newton's second law says that the acceleration of an object depends on two factor i.e. net force that is acting on object and object's mass.
I think everytime they swim away, the water pushes the enemy back, which makes the octopus go faster. Every action has an equal and opposite reaction. Hope this helps.
