The particles of objects have both kinetic and potential energy because these forces are drive by the force of motion or stillness of an object. Potential energy is the a type of energy which an object possess however without motion. Kinetic energy in the other hand, is the energy in motion or if the object moves along from one space to another with respect to time. They both have these two energies by the presence of atoms in these entities.
Particles of objects have both kinetic and potential energy due to the fundamental principles of classical mechanics. Kinetic energy is associated with motion; this energy is observed when particles are moving. For example, when a ball is falling, its motion means it possesses kinetic energy.
On the other hand, potential energy is related to the position, composition, or condition of an object. A ball at the peak of its bounce is momentarily stationary, yet it has potential energy due to its elevated position and the gravitational force acting upon it. Once in motion, the ball's potential energy converts back into kinetic energy.
In physical interactions, such as collisions or vibrations, energy can transfer from one particle to another, and there can be a conversion between kinetic and potential energy. The conservation of energy principle mandates that the total energy within a closed system remains constant, though the form of energy may change back and forth between kinetic and potential.
Particles have both kinetic and potential energy due to their states of motion and position. Kinetic energy arises from motion, while potential energy is stored based on an object's position. Energy can shift between these two types, exemplified by a swinging pendulum or a falling object.
