Answers
Answer:
1. Power is the rate of doing work
2. The SI unit of work and energy is joule
3. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position.
4. Power is rate of doing work or the rate at which energy is supplied to the system
5.Energy transformation, also known as energy conversion, is the process of changing energy from one form to another

Explanation:
1.It is the amount of energy consumed per unit time. The unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine).
2.The SI unit of energy/work is the joule (J), named for English physicist James Prescott Joule (1818 - 1889). Joule discovered the relationship between heat and mechanical work, which led to the development of the laws of thermodynamics.
3.Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
