Question

Simone created a chart to summarize the energy transformations that take place when energy from the wind is used to generate electricity.

Which best completes the chart?

Answer 1

Wind power is produced from the wind turbines or sails that uses air flow to convert it into mechanical power. It is an alternative to fossil fuel burning, it is all around, renewable, clean, produces no greenhouse gases and uses little land. The advantages of wind power have been greatly praised by many. However, it has disadvantages. Wind power especially at farm is noisy and may spoil the view for their neighboring people. Also the amount of electricity depends on the strength of the wind. If no wind is around, no electricity is produced.

Answer 2

Answer;

-kinetic energy transformed to mechanical energy

Step-by-step explanation;

-When the blades are moved or spins (rotational motion) some part of the kinetic energy of the wind is transformed into rotational kinetic energy of the the blades, which makes an axis rotate generating the electricity.

-KInetic energy is mechanical energy (mechanical energy is basically kinetic energy and gravitational potential energy).

-Therefore, the kinetic energy of the wind is transformed into kinetic energy of the windmill (mechanical energy) and it is then transformed into electrical energy.
