Which needs less force to be moved? A roller skate on its side or a roller skate on its wheels?

I need to help making a procedure showing which one is true. Can anyone help? My items that need to be used are:





2 roller skates


2 rubber bands, same size


1 yardstick





I'd really appreciate any help I can get!! Thanks! :)

attach bands to skates,pull band until skate moves , measure length of band when pulling - longer band more force
Reply:What this is a no brain-er. The one on it's wheels has less friction and will move easily, where as the one on it's side has a lot of drag.
