Consider the movement of a stone thrown vertically upwards. What kind of energy transformation occurs when the stone is raised to its top? And with his subsequent movement
The stone was thrown – Ek – max, En = 0; further kinetic energy decreases, potential increases; at the top point En – max, Ek = 0; further kinetic energy increases, potential energy decreases, at the moment of impact all energy is transferred into internal energy.
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.
