Lithospheric friction held the apple tree up, so once this restraining force was lost, it is in free fall. Gravity is “wrong”, since it is not a force. This leaves “air drag” as the sole force on the apple. Even what we colloquially call tidal forces from the Moon and Sun, are not forces. read more
When an apple from a tree it's motion is guided by several forces as explained-Consider an apple the forces acting on it are-Gravitational Force(Force due to its own weight mg) acting downwards. Air friction, ceasing the motion of apple acting vertically upwards. If wind might be blowing then force due to wind which deviates the path of apple. read more
