Angular lines refer to straight or sharp lines that create a sense of energy, movement, and dynamism in a design. They are often used to convey a feeling of strength, stability, and modernity. These lines can be found in various artistic and design contexts, such as architecture, graphic design, and fashion.

As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
We can measure only angular sizes and angular distances for objects in the sky because they are very far away from us, making their physical size and distance impractical to measure directly. By measuring their angular sizes and distances, we can calculate properties such as their actual size and distance using geometric principles and known relationships.
The concept of angular momentum was developed by Sir Isaac Newton in the 17th century. He observed that objects in motion can possess a type of rotational momentum, which is now known as angular momentum.
In orbital motion, the angular momentum of the system is constant if there is no external torque acting on the system. This is a result of the conservation of angular momentum, where the product of the rotating body's moment of inertia and angular velocity remains constant unless acted upon by an external torque.
Longitude lines run north-south from the North Pole to the South Pole. They measure the angular distance east or west of the Prime Meridian, which is the starting point for longitude at 0 degrees.
