The twisting motion of the foot that turns the sole inward is known as inversion. It involves the movement where the sole of the foot faces inwards towards the midline of the body. This movement is often associated with ankle sprains or instability.
Rotation.
An electric motor turns electrical energy into mechanical energy, which is used to produce motion or perform work.
A bird flying in the sky demonstrates translational motion as it moves in a straight line through the air. Additionally, the wing flapping creates rotational motion as the bird turns and changes direction in flight.
Pronation
A bus typically moves in a forward motion, propelled by its engine and driven by a driver. It can also make turns, stops, and accelerations as it navigates through traffic and follows its route.

Pronation. This motion involves the inward rotation of the foot, typically occurring during walking or running to help absorb shock and distribute weight evenly across the foot. Overpronation or underpronation can lead to biomechanical issues and potential injuries.
Pronation is the motion that turns the palm of the hand downward or backward.
Entropion is the condition where the lower eyelid turns inward, causing the eyelashes to rub against the eye. It can lead to irritation, redness, and sensitivity to light. Treatment may involve surgery to correct the position of the eyelid.
Rotation.
The foot generally turns inward so that the leg and foot look somewhat like the letter J
Pronation
The condition where the edge of the eyelid turns inward is called entropion. This can cause the eyelashes to rub against the cornea, leading to discomfort, irritation, and potential damage to the eye. Entropion can occur due to aging, scarring, or other factors affecting the eyelid's structure. Treatment typically involves surgery to reposition the eyelid.
Foot eversion refers to the movement of the foot that turns the sole outward, away from the midline of the body. This motion primarily involves the subtalar joint and is crucial for balance and stability while walking or running on uneven surfaces. Eversion is often contrasted with inversion, where the sole of the foot turns inward. It plays a significant role in various athletic activities and can impact overall foot mechanics.
A blind axle is an axle which turns but does not communicate motion.
generator
Pronation is the motion that turns the palm of the hand downward or backwards. It involves rotating the forearm so that the palm faces posteriorly or downwards.
