What is Motion without Friction?

Motion without friction is a phenomenon in which an object is in motion whilst its surface is not in contact with other surfaces. An example of such motion is that of a hovercraft.


As you can see in the image, the hovercrafts's bottom surface and the ground do not actually make contact, it is thanks to the continuous movement of air which pushes the hovercraft with enough force to keep it off the ground.

  1. So, before you adopt a bunny test Luxury Dog Carrier the personality first if the bunny likes to be touched and held. Also, talk Small Dog Collars to the breeder about the personality of the particular bunny you would like to adopt so you know how to treat the bunny.
