Here's why:
* Linear speed refers to the rate at which an object changes its position along a straight line.
* Tangential speed refers to the linear speed of an object moving along a circular path. It is called tangential because the direction of the object's velocity is always tangent to the circle at its current position.
Think of it like this: if you were to draw a line that touches the circle at the point where the object is located, the object's velocity would be parallel to that line. This line is called a tangent line.
