# Given Newton's Third Law, why does it hurt more to be tackled than to tackle someone else? [closed]

In other words, are there more underlying physics concepts occurring in, say, a football tackle? According to Newton's third law, the individual doing the tackling should feel the same force as the person being tackled, in the opposite direction. However, it is the person being tackled who usually gets injured.

Edit: It seems my question is more biological than physical. Thanks for the explanations, though.

• In football, momentum equals mass times velocity times emotion: $p = mv\epsilon$, where $0 \le \epsilon \le 110$%. – JEB Mar 11 at 0:53
