Answer
Energy is transferred by a force moving an object.
Explanation
Each of the options provided describes a type of energy transfer. However, in the context of mechanical work, we need to identify the option that directly relates to this concept.- Energy is transferred by a force moving an object: This describes the transfer of mechanical energy. When a force is applied to an object and the object moves, work is done, and energy is transferred.- Energy is transferred as a wave: This describes the transfer of energy in wave motion, which includes both mechanical waves (such as sound waves) and electromagnetic waves (such as light waves).- Energy is transferred by a charge moving: This describes the transfer of electrical energy, specifically when an electrical charge moves through a conductor.- Energy is transferred from a hotter to a cooler object: This describes the transfer of thermal energy, which occurs when heat moves from a warmer object to a cooler one.Given the context of the question, the best description of how energy is transferred by mechanical work is when a force moves an object. This is because mechanical work involves the application of force to move an object, which results in the transfer of energy.
