Goal posts at the ends of football fields are padded as a safety measure for players who might run into them. How
does thick padding around the goal post reduce injuries
to players?

It would be awesome if you could use a sample response

Goal posts at the end of football field are padded as a safety measure to players who might run into them,these thick paddings of the goal posts are done to prevent injuries to the players because the padding of the goal post increases the time of impact and this in-turn decreases the force on the the players body or the force it will have when a player's body hit against it and therefore decreasing the force applied to bring the player to a stop.

We can also say that it increases the time of collision between the player's body and the post.
