does it take wheels for precession to happen? can precession be applied to ice skates, for example?
Would it be the torque?berkeman said:Welcome to PhysicsForums.
Assuming you mean precession of a spinning ice skater (not of their skates), it should happen. What makes a gyroscope precess? Spinning angular momentum is one part; what is the other part that causes precession? What could you do to an ice skater in a spin that would cause this effect?

A person leans to the side riding his bike to make the turn. I wanted to know about a person leaning on ice skates to make the turn, just like the person on the bike.A.T. said:How should we know? You have not described any specific scenario.

So a high speed ice skater is no more stable than a low speed ice skater?A.T. said:I don't think precession plays a role in this case.
Moving fast by itself does not create stability against falling over to the side.gabriel barata said:So a high speed ice skater is no more stable than a low speed ice skater?
Precession refers to the phenomenon where the axis of rotation of a spinning object changes direction due to external forces acting on it. In the case of high-speed ice skaters, precession helps to stabilize their movements by counteracting any external forces that may cause them to lose balance. This is because the precession force acts perpendicular to the direction of the external force, thus keeping the skater upright and stable.
While precession plays a significant role in maintaining the stability of high-speed ice skaters, it is not the only factor at play. Other factors such as the skater's center of mass, body positioning, and muscle control also contribute to their stability. Precession is just one of the mechanisms that helps to keep the skater balanced and in control of their movements.
No, precession and angular momentum are two different concepts. Angular momentum refers to the rotational momentum of an object, while precession refers to the change in direction of an object's axis of rotation. Precession can affect the angular momentum of an object, but they are not interchangeable terms.
Precession is a fundamental principle in many sports and activities that involve spinning or rotating movements. Some examples include figure skating, gymnastics, diving, and even martial arts. In these activities, precession helps to maintain the stability and control of the athlete's movements, allowing them to perform complex maneuvers with precision.
Yes, precession can be manipulated to improve a high-speed ice skater's performance. Skaters can use their body positioning and muscle control to control the direction and magnitude of the precession force, which can help them maintain balance and execute more complex movements. Additionally, coaches and trainers can also use precession as a training tool to improve an athlete's stability and control on the ice.
