Is it possible for potential energy to change into kinetic energy AND work ?
Energy must always be accounted for. If you start with something with lots of potential energy, say a brick 10m above the ground, and drop it – by the time it gets to the ground, it will no longer have any gravitational potential energy. The potential energy will have transferred into kinetic energy ( the brick is moving quickly right before it strikes the ground). The maximum potential energy value at the start and the maximum kinetic energy at the end will be equal. (assuming no friction- which would cause some energy to turn into heat or sound or light– which is still accounted for and is not disappearing) So yes, potential energy is often converted to kinetic and vice versa. As for work… Work is just a change in energy- the energy required to accelerate something or do something. If you through a ball and give it 10 J of kinetic energy, you have done 10 J of work on that ball. So really work isn’t something potential energy turns into it is just another way of expressing what th
