Hi, it can be both ways,
Friction is the method of pull and push
Friction acts in all directions.
Push
friction
your face. that's what it is.
Push, pull and skid.
Friction Interaction is a push or pull factor of your object rubbing against the ground.
It involves pushing, gravity, and friction.
Because you have to overcome static friction when you push or pull for it to move. This resists the force, then when overcome it will jerk, then slide with sliding friction resisting.
Push, pull and skid.
Friction is a sticky force that appears when 2 objects rub against each other. If you push or pull slowly friction helps pull or push the tower along with the bottom coin. If you push or pull quickly, the coins still rub, but the friction force doesn't have time to get the stack moving. So the coin shoots out without pulling the tower with it.
Well, there's pull, push, friction and gravity.
