Turning the coarse adjustment knob of a microscope downwards brings the objective lens closer to the specimen, allowing for initial focusing at low magnification. This is useful for quickly bringing the specimen into view. Turning the coarse adjustment knob upwards moves the objective lens away from the specimen, enabling a higher focal point for fine-tuning the focus at higher magnifications. It is essential to use the coarse adjustment first to avoid crashing the objective lens into the specimen, which can damage both the lens and the specimen.
Cause if it is facing upwards it face the space and will not and never reflect downwards
Stalactites point downwards from the ceiling of a cave, while stalagmites point upwards from the cave floor. Over time, these formations can grow towards one another and eventually meet to form a column.
Rockets do not use lift like airplanes do in takeoff. Instead, they rely on powerful engines and thrust to propel them upwards. Rockets work on the principle of action and reaction, where the force of the exhaust gases being expelled downwards generates an equal and opposite force that pushes the rocket upwards.
The stalactites hang from the ceiling, and the stalagmites are on the ground.

When turning the coarse adjustment on a microscope upwards or downwards, the distance between the tube and the stage changes. This changes the detail of what you can see of the specimen you are examining.

Turning the course adjustment knob upwards or downwards on a microscope moves the stage closer to or further from the objective lens, allowing you to bring the specimen into focus. This adjustment is used to quickly bring the specimen into view at low magnification.

Turning the course upwards or downwards adjusts the pitch of the propeller blades, allowing the pilot to control the aircraft's speed and engine RPM. Increasing the pitch by turning it upwards generates more thrust but requires more power, while decreasing the pitch by turning it downwards decreases thrust and power requirement.

The coarse adjustment is used to focus in on the specimen. It accomplishes this by moving the stage or the upper part of the microscope.
