is there difference if you pull a block down a hill or if you push a block down a hill. Or if you push a block up a hill or pull it up ? For example if you PULL a block down a hill it would be F+Fg||-fk =ma (the force you are using +Fsinθ - kinetic friction =ma. Would this change if you PUSH the block down? ​
