What is tangential?

Hint: In order to solve this question first of all we will know what is tangent then we will study tangential in full detail then further we will study the importance of tangential in physics. So the tangent is the line which is touching any curve only one point so that is called the tangent of that curve.

Complete step by step solution:
For solving this question we will first study the tangent:
Tangent: It is the line which is touching any curve at only one point.
From this we can get the idea that any curve can have different tangents at the different points. In fact it is also possible that any curve has an infinite number of tangents.
Now to learn about the tangential we will take the help of the diagram:

Tangential means:
1.a : touching lightly : incidental, peripheral tangential involvement also : of little relevance arguments tangential to the main point.
b : divergent, digressive.
2: of, relating to, or of the nature of a tangent.
3: acting along or lying in tangential forces.

Note: Tangential force is defined as the force acting on a moving body in the direction of the tangent to the curved path of the body. If the velocity of the object is positive, the acceleration will be negative. This is called a tangential force.
