(a)
Interpretation:
The conversion of kinetic energy into potential energy or the vice versa in the given process has to be determined.
Concept introduction:
Energy:
Energy is the capacity to do work, and can neither be created nor destroyed. Generally,
Types of energy:
Kinetic energy is the energy associated with motion. Thermal energy, mechanical energy, electrical energy, and acoustic energy are categorized in kinetic energy.
Potential energy is the energy results from an object’s position or state. Gravitational energy, chemical energy, and electrostatic energy are categorized in potential energy.
(b)
Interpretation:
The conversion of kinetic energy into potential energy or the vice versa in the given has to be determined.
