No, at the moment of collision, the kinetic energy of the bodies involved is not directly converted into potential energy. Kinetic energy is the energy possessed by an object due to its motion, while potential energy is the energy associated with an object's position or condition.
During a collision, the kinetic energy of the bodies involved may change, but it is typically converted into other forms of energy such as deformation energy, heat, or sound. In an elastic collision, where there is no net loss of kinetic energy, the energy is redistributed between the bodies involved. In an inelastic collision, however, some kinetic energy may be lost due to deformation or other factors.
Potential energy, on the other hand, is associated with the position of an object or its interaction with a force field, such as gravitational potential energy or elastic potential energy. It is not directly involved in the moment of collision itself.
It's worth noting that the concept of energy is conserved in a closed system, according to the law of conservation of energy. The total energy remains constant, but it may change form or be transferred between different types of energy during a collision or any other physical process.
