In this video of a bunny running up the stairs, the bunny is doing work. When the bunny runs up the stairs, its force (its weight) and the distance vertically that it travels are multiplied and result in work. This bunny does not produce as much work as either a bunny running up a higher staircase or a larger bunny who weighs more resulting in a larger force. While the bunny is running, it is also producing power. The bunny's power is its work divided by the time it take for the bunny to run up the stairs in seconds. So the bunny is doing work and producing power in the video.
