Tangential Speed is equal to the instantaneous linear speed of the particle at any point on the curved path. Tangential speed at any point is equal to the multiplication of the radius of curvature and angular speed at a particular point on the curved path. Angular speed is defined as the time rate of change of the angular displacement along the curved path.
The tangent at a given point on a curve is the straight line that just touches the curve at the given point. Leibniz defined this as being the straight line through two infinitesimally close points on the curve at that point, leading to the relationship between the slope of the tangent and the first derivative of the function (if both exist) at that point.
