Can Scalar Field Exert Torque on Particle?

Click For Summary
SUMMARY

A scalar field does not directly exert torque on a classical point particle; however, it can influence angular momentum under specific conditions. The gravitational scalar potential exemplifies this, as it can lead to rotating motion while conserving angular momentum. Gravitational coupling, such as the Earth-Moon system, demonstrates how angular momentum changes in non-point particles. Additionally, scalar fields may require further interactions, such as hydraulic pressure, to manifest vector characteristics that can exert forces.

Can a scalar field exert a torque on a particle?
 
Physics news on Phys.org
It is unclear how you can get a torque on a classical point particle ... however, can you think of a scalar field in nature that shows characteristics of torque (a change in angular momentum). i.e. the gravitational scalar potential can result in rotating motion - but it conserves angular momentum. You can get gravitational coupling - i.e. earth-moon - where angular momentum of each individual object changes: but these are not point-particles.
 
Often, the scalar field may not by itself related to motion but require further conditions, like hydraulic pressure in a bucket is a scalar but on the walls, it is coupled with the area vector and becomes a vector and could force and bend which could be observed with flexible walls.
