The angular momentum of a moving body remains unchanged unless an external torque is exerted on the moving body. Angular momentum denotes rotational motion around the axis in any object depending upon its distribution of mass and rotation velocity. By principle, there would be a lack of a change in time with respect to total angular momentum when no torque external to a system is given to it.
Rotational force, referred to as torque, affects the angular momentum due to a change in speed of rotation or rotation direction. With the application of external torque in a body, its angular momentum changes. Nonetheless, if torque is not external, the angular momentum remains unaffected, and its rotational motion keeps constant.
This concept is evident in various situations. For example, a figure skater spinning faster by pulling their arms inward demonstrates conservation of angular momentum. The skater changes the distribution of mass in their body without involving any external torque. Similarly, planets orbiting the Sun conserve their angular momentum because no external torque significantly affects their motion.
In essence, angular momentum remains constant only when there is no external torque; it ensures steady rotational motion. Therefore, a moving body will retain its angular momentum if no external torque is applied.

We can look at the forces acting on the sphere to find the linear acceleration of a solid sphere rolling down an inclined plane set at an angle of 30 degrees with the horizontal. The main forces are the gravitational force, which is the cause of the motion of the sphere, and the frictional force, which is required for rolling motion.
When the sphere rolls down the incline, gravity pulls it down, but the angle of the incline determines how this force is distributed. The gravitational force can be divided into two components: one that acts parallel to the slope, propelling the sphere downwards, and another that acts perpendicular to the slope, influencing the normal force experienced by the sphere.
As the sphere rolls without slipping, it is undergoing both translation and rotation simultaneously. The resulting linear acceleration would then be developed from the motion dynamics of a rolling sphere.
For a solid sphere rolling on a 30-degree incline, the acceleration in the line of motion ends up being just some fraction of g, weighted by the sine of the angle of inclination. In this problem, the specified conditions allow calculating the acceleration as the sphere rolls down the ramp to be 5g/14, so this is the right solution.

The angular velocity vector is thus an important component, as it deals with the magnitude of rate, together with its direction in relation to an object rotating. Thereby, through using the right-hand rule to get the correct angle, in finding the axial position, it depicts how to read in a general plan of determination to identify any other axis’ resultant vector related with angular speed along its specified position.
This directionality is crucial in defining the motion in three-dimensional space. For instance, take a spinning wheel. The angular velocity vector does not lie in the plane of the wheel or along its edge. Instead, it points along the axis of the wheel, either upwards or downwards, depending on the direction of rotation.
Other options, such as the tangent to the circular path or the inward or outward radius, relate to linear motion or forces acting in circular paths. These are not suitable for defining angular velocity. The axis of rotation uniquely defines the vector’s direction, distinguishing rotational motion from linear dynamics.
This concept is fundamental in analyzing rotational phenomena such as torque, angular momentum, and rotational equilibrium; thus, it is of paramount importance in both physics and engineering.
