does work equal change in potential energy or change in kinetic energy?
UrbanXrisis said:I read that something =(-dPE)/(dt)
not I for got what. Any ideas? Power=(-dPE)/(dt)?

Do you know the difference between conservative and non-conservative forces?
Potential energy is the energy an object has due to its position or shape, while kinetic energy is the energy an object has due to its motion. Potential energy can be converted into kinetic energy and vice versa.
Work is the transfer of energy from one form to another. When work is done on an object, it gains kinetic energy. Similarly, when an object does work, it loses kinetic energy and gains potential energy.
An object's potential energy is affected by its mass, height, and gravitational force. Its kinetic energy is affected by its mass and velocity.
Yes, potential and kinetic energy can be converted into other forms of energy such as thermal, electrical, or sound energy. This is known as the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred.
Potential and kinetic energy are used in many everyday activities, such as riding a bike, throwing a ball, or using a rollercoaster. They are also important in understanding how energy is transferred and transformed in various systems, from simple machines to complex power plants.
