This makes sense, thank you.
I think in my head I was mixing up "force" and "power"; it's clear that with two cubes travelling linearly at the same velocity, the one that's also rapidly spinning has more energy.
That it can take varying amounts of energy to apply the same amount of force to the same object was the missing piece for me, since I was thinking of force as power.
- amluto 4y agoIt’s fairly easy to demonstrate this if you have a friend with a bicycle. Have someone on a bike stay still and hold the brakes, and press firmly on their back. It’s easy. Then have them bike at a slow jogging pace, run along with them, and try to apply the same force on their back. It will be hard work.
