Push and pull

[coolone_888]

Why is it easier to move a chair across the floor by pulling then by pushing it?

[SuckIt]

push the chair at the bottom near it's legs, then try again ;)

also when pushing, you're pushing down (vertical component of force) so creates more friction because F=\mu.R etc etc etc

if you were pulling and pushing perfectly in the plane of the chair then it would be just as easy/hard etc etc...
someone else will put that into English for you

so it is easier to pull a chair across the floor because if you push you just add more friction?
