Give examples of bodies (systems of interacting bodies) with potential energy. The potential energy of the body depends on such physical quantities. Write down the formulas expressing these dependencies in a notebook.
The potential energy is provided by water in rivers held by a dam; the energy of compressed and twisted springs, which are used in mechanical watches, wind-up toys; potential energy of compressed gas is used in the operation of heat engines.
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.
