* Gravity: The primary force acting on the tree is gravity. Gravity always pulls objects towards the center of the Earth, which is downwards.
* Slope: While the mountain cliff provides an incline, gravity's pull is stronger than the slope's influence. The tree will slide down the cliff due to gravity.
* Direction of Fall: The direction of the fall will depend on the angle of the cliff and the tree's position on the cliff. However, the fall will always be downwards towards the Earth.
It's important to note that the tree might not fall straight down. It could tumble or slide depending on the terrain.
