Compare at perihelion and aphelion the angular and linear velocities of a comet moving along an ellipse with an eccentricity of 1/3 and an eccentricity of 0.75.
At perihelion, the linear velocity is twice, and the angular velocity is four times greater than at aphelion. At perihelion, the linear velocity is 7 times, and the angular velocity is 49 times greater than at aphelion.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
