introduction to energy

which statement best defines the relationship between work and energy?
work can transfer energy between objects and increase radiant energy.
work can transfer energy between objects and cause a change in the form of energy.
work can transfer energy between objects and decrease nuclear energy.
work can transfer energy between objects and cause a change in the amount of total energy.

Explanation:

• According to the law of conservation of energy, the total amount of energy in a closed system remains constant. So the option that says work causes a change in the amount of total energy is incorrect.
• Work is a way of transferring energy. It can transfer energy between objects. And when work is done, it can cause a change in the form of energy (e.g., mechanical work can convert kinetic energy to potential energy and vice - versa). There is no specific reason to say it always increases radiant energy or decreases nuclear energy. Radiant energy increase or nuclear energy decrease are very specific and not general statements about the relationship between work and energy.

Answer:

Work can transfer energy between objects and cause a change in the form of energy.
