The upward force is called lift, while the downward force is called weight or gravity.
Gravity (downwards), and air resistance (upwards).
When a yo-yo is motionless, the forces acting on it are balanced. There are two main forces: gravity acting downward and the normal force exerted by the surface it rests on acting upwards. These forces are equal in magnitude and opposite in direction, resulting in zero net force and causing the yo-yo to remain motionless.
The girl going uphill is pushing against gravity and frictional forces. Gravity is pulling her body downward, making it harder for her to move upwards. Frictional forces between her feet and the ground are also opposing the motion, requiring extra effort to overcome.
When a skydiver is accelerating downward, the forces are unbalanced. The force of gravity acting downward on the skydiver is greater than the air resistance force pushing upward, causing the skydiver to accelerate downward.
The three forces acting on a book could include gravity, which pulls the book downward towards the Earth; the normal force exerted by the surface the book is resting on, which pushes the book upwards to balance gravity; and friction if the book is being pushed or pulled across a surface.

No. Only downward and to the right.

The load will move upwards.

No, it isn't. If you mean slip as in 'fall over', then no. The correct world would be 'slide'.

Cause if it is facing upwards it face the space and will not and never reflect downwards
