Question

When rollerblading,why is a fall less harmful on a wooden floor than on a concrete floor that has less give?Explain in terms of impulse and momentum.

Answer 1

go on google and type in "impulse and momentum upon impact explanation" and click on the link 4th from the top

p.s. i know its probably already obvious but i think it's just the density imbalances

Answer 2

When rollerblading, a fall is less harmful on a wooden floor than on a concrete floor that has less give because the concrete surface is much harder than the wooden floor, so when the roller-blader falls, he falls on a larger force in a shorter amount of time. The amount of damage depends on the size of the force, so a floor that slows you down more gradually causes less damage since it applies less force.
