In low gravity- less effort and slow motion in upward and downward movement. in higher gravity - more effort and slow motion in upward movement and vice versa for downward movement.

No, gravity is a downward force.

In low gravity- less effort and slow motion in upward and downward movement. in higher gravity - more effort and slow motion in upward movement and vice versa for downward movement.
Just add the forces on the desk. Use a positive sign for one direction, a negative sign for the opposite direction.
gravity
In the act of "throwing", the thrower imparts an upward velocity to the object, by temporarily applying an upward force to it that's greater than the downward force of gravity. During that brief period, the sum of the forces on the object is directed upward, so it accelerates in that direction. After the throwing ends, however, the only force on the object is the force of gravity, directed downward, so its acceleration is downward. That means that the upward velocity becomes smaller and smaller, until it's zero at the peak of the arc, and the velocity then becomes downward as the object begins to fall from its peak..
By applying an upward force on the object that is greater than the downward force of Earth's gravity acting on it. Somewhat the same thing that you do with your leg muscles when you walk upstairs, or go in for a jump shot.
