Finite angular displacements are not vectors because they do not adhere to the principles of vector addition and subtraction. While they can be represented as a rotation about a specific axis, they do not possess a unique direction in the same way that linear vectors do. Additionally, angular displacements can lead to ambiguities, such as rotating in opposite directions yielding the same endpoint but different angular values. Therefore, they are better described using concepts like angular momentum or rotation matrices rather than as simple vectors.

Why finite angular displacement is not a vector?
No no its a true vector for infinite angular displacement
Why finite angular displacement is not a true vector?
No no its a true vector for infinite angular displacement
What are the units for angular displacement?
Angular displacement is measured in radians (rad) or degrees (°).
Is angular displacement is a vector?
angular displacement is a vector quantity when theta (angle) is small, otherwise it is scalar.
Is finite rotation a vector?
Finite rotation can be represented as a vector in three-dimensional space, but it is more accurately described using a rotation matrix or a quaternion. In physics and mathematics, rotations are often treated as transformations rather than simple vectors, as they involve orientation changes rather than just magnitude and direction. While one can use angular displacement vectors, these do not fully capture the properties of rotation, such as the non-commutative nature of rotational operations. Thus, while finite rotation can be associated with a vector-like representation, it is best understood through more complex mathematical structures.
What is the unit of angular displacement?
Radian is the unit for angular displacement is SI system of units.
How can one determine the angular displacement of an object using the method of finding angular displacement?
To determine the angular displacement of an object using the method of finding angular displacement, you can measure the initial and final positions of the object and calculate the difference between them. This difference represents the angular displacement, which is the change in the object's orientation or position around a fixed point.
What is the right-hand rule for angular displacement?
The right-hand rule for angular displacement states that if you align your fingers in the direction of rotation, your thumb points in the direction of the angular displacement vector. This rule helps determine the direction of rotation or angular displacement in a given scenario.
What is magnitude of the two displacement vectors?
The magnitude of two displacement vectors, of magnitude x and y, is sqrt(x2 + y2)
What are the vectors?
Vectors are quantities that have both value and direction. Such as displacement and Velocity.
Is angular displacement and angular velocity the same?
No, angular displacement refers to the change in angle of an object relative to a reference point, while angular velocity is the rate at which an object changes its angle over time. Angular displacement is a scalar quantity, measured in radians, while angular velocity is a vector quantity with direction and magnitude, measured in radians per second.
What are the dimensions of angular displacement?
Angular displacement dimensions are radians. There are ( 2 ) ( pi ) radians or 360 degrees in one complete circle of displacement. Some treat angular displacement as having no dimensions; however, this is a poor and misleading practice. Angular velocity commonly has dimensions of rad/s or radians per second.
