    Why Is a Pillow Safer Than a Rock If Both Fall at the Same Speed?

    The latter will have a higher acceleration and thus by Newton's 2nd law, a greater force. Thanks!

    Why Is a Pillow Safer Than a Rock If Both Fall at the Same Speed?

    That kind of makes intuitive sense now that you mention it. I guess I had a slightly wrong idea of impulse. I'm starting to grasp it now... Longer compression time = "greater distance as it comes to rest", and hence the smaller magnitude of acceleration as it takes more time I think I'm on...

    Why Is a Pillow Safer Than a Rock If Both Fall at the Same Speed?

    The line I'm having trouble with is, "The pillow ... travels through a greater distance as it comes to rest"

    It would be greater for the rock than a pillow? Also! By Newton's 3rd law since my head would exert less force on the pillow, the pillow would also exert less force on my head, because of the smaller impulse. Is that valid?

    Why Is a Pillow Safer Than a Rock If Both Fall at the Same Speed?

    Hi I'm a first year Physics Undergrad and I never quite got satisfied with the answer to this question: "Why would you be rather hit with a pillow than a rock, if they reach the ground at the same time?" I know the obvious answer is because the pillow is soft. But how would you describe...
