In physics, what unit is commonly used for measuring angles?

The most appropriate choice for measuring angles in physics is that both radians and degrees are commonly used units. Radians are particularly favored in many physics applications because they provide a direct relationship between the length of an arc and the radius of the circle, making calculations involving circular motion and oscillations more straightforward.

Degrees, on the other hand, are more commonly used in everyday contexts and for practical applications where angles are measured in terms of fractions of a circle. While both units serve their purposes, radians are more convenient in mathematical equations and trigonometric functions used in physics.

Milliradians are another unit used for measuring small angles, but they are less commonly referenced in general physics contexts compared to radians and degrees. Therefore, understanding that both radians and degrees can be valid units for measuring angles in physics is essential for applying the appropriate unit based on context.
