I agree with that because that's the same formula I use for when a person hits the ground. lol. A cat with it's legs tide dropped from 10 feet isn't going to suffer the same injuries as an elephant dropped from 10 feet. This is why it doesn't hurt when toddlers jump on their parents who are laying down don't hurt.
Mass will still play a role of creating the force provided that the person can move the mass at a significant speed.. A person that weighs 150 pounds is going to have a harder punch than a person weighing 600 pounds. That same 600 pound person if thrown to the ground is going to have more damage than a 150 pound person simply because the skeleton will absorb some of the impact from weight. The OP's question are very general so I'm sure there will be even more perspectives to come
There are all kinds of effects that cause injury in falling. The cushion of the impacted area for example.
You fall into a bed in your room or trip on floor in your room and down you go. Even jumping on soft nice pillows can cause injury.
You fall into a bed of downy feathers, you might survive. You fall onto a hard cement sidewalk, not so likely.
And how you fall also affects the outcome. You fall first on your head, not good. You fall splayed out onto your back, which distributes the impact force over a larger area, that might be better.
You fall on your head really bad, you fall on your side or arms okay, you fall on you back better. More surface area if you fall on you back to distributes the impact force.
We can survive an impact of about 60 Gs to 70 Gs.
