Pronation
The bending motion of the wrist is called flexion and extension. Flexion involves moving the palm of the hand closer to the forearm, while extension involves moving the palm of the hand away from the forearm.
The opposing force in this situation is gravity pulling the magazine downward.
The hand wave is a simple repetitive motion where the hand is raised and moved from side to side in a greeting or acknowledgement gesture. It typically involves moving the wrist and forearm while keeping the fingers and palm relatively stationary. The motion can vary in speed and amplitude depending on the cultural context or personal style.
My hand moves in a rhythmic back-and-forth motion, with my palm facing down and fingers slightly curved. As I press down on the surface, I generate the pulse by exerting force and releasing it quickly, repeating the action with a consistent tempo. This motion creates the pulsating wave that conveys the energy through my hand.

Pronation
Turning the palm backward or downward is called pronation. This movement involves rotation of the forearm so that the palm faces downward or backward.

pronation
When the palm of the hand faces backward, the radius crosses over the ulna in the forearm. This movement helps to rotate the forearm and allow the hand to face backward.
To indicate that you are braking while riding a bicycle, you should use your left hand to extend downward with your palm facing backward.
A movement that turns the palm downward is called pronation. This occurs when the forearm rotates, causing the palm to face downward or backward. Pronation is commonly involved in actions such as typing on a keyboard or pushing objects away. It contrasts with supination, where the palm faces upward.
The term that means turning the palm upward or forward is "supination." This movement is commonly used in anatomy to describe the position of the forearm and hand. In contrast, the opposite movement, where the palm is turned downward or backward, is called "pronation."
In American Sign Language (ASL), the sign for "obey" involves making a flat hand shape, palm facing down, and moving it in a downward motion.
In American Sign Language (ASL), you can sign "goodnight" by using your dominant hand to make a flat palm facing downward, and then moving your hand in a downward motion close to your body. It's a simple and common sign used to wish someone a peaceful night.
