... They exert forces on one another. Newton’s third law states that the force between them is exactly the same, but opposite in direction. They touch each other (and exert the same force on one another) for the same amount of time. This will cause an equal but opposite change in their momenta, conservi ...

Ch 7 Impulse and Momentum
... 3rd law that forces always occur in pairs (action-reaction), so when two objects interact the forces they apply on each other must be equal in magnitude and opposite in direction. Since the forces are of equal magnitude and they act over the same amount of time, the impulse on each object must also ...

... The change in momentum, i.e. the impulse, is the same in both experiments, since the initial velocity of your fist (before the collision) was the same and the final velocity was the same (vf = 0 m/s) in both experiment. The difference was the surface material your fist crashed into: Hard table top v ...
