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 absorbs the force of the impact- slowing down the impact speed and converting that force onto the padding.

Explanation:

The padding around the goal post increases the time of the collision between the player and the post, which decreases the force exerted to bring the player to a stop
