Can cinematics have physics applied liek solcid pobects, floor and water waves or is it just blueprint games?

Is it possible to apply physics to cinemantics, ie make a slide solid and boats floating on waves?

Ive been ytyignn to make a music video like dance video and have had really hard time gettign a character clubing up a kids slide and sliding down tyign to manouver and animation the character in thin air and probelsm with the character droppign through. I also have a harbour of yachts, it would be nice to see them bobbing up or down but this is not a game more an animated sequece
