Why do giant things in movies move in slow motion?

Is that realistic? Do ants see us like that?

No matter how big you are, forces like gravity are consistent. A human jumping off a platform as high as themselves hits the ground in about half a second. A giant doing the same thing would have to travel a much lager distance, but gravity pulls them at the same distance over time as the regular human, so it takes a lot longer for them to fall “their own height”.

Even ordinary feats like walking have to take this into account. When you raise a leg into the air, it comes down either by gravity or your own muscle. If you try to use muscle to put it down faster than gravity… you can do it, but physics would actually respond by lifting the rest of your body. I imagine a giant trying to run in place – and being able to move seemingly as fast as a normal human would despite their massive body weight – would spend way more time with both feet off the ground at the same time than a human would.

But of course, the actors are normal humans on a set designed to look small so the humans seem huge. It makes the physics inconsistent for this world, such as gravity being too strong. So, the film maker slows down the footage to make it look closer to realistic. Now gravity seems about right.
