What Is Energy | Energy Energy Energy?

For the activities listed below, list one way in which energy is converted, one example of kinetic energy involved, and one example of potential energy involved.a. making a mealb. traveling to schoolc. moving to a new apartmentd. playing in a rock band

Potential energy: The energy of a particle from position, or condition, rather than motion. A raised weight, coiled spring, or charged battery has potential energy.kinetic energy:The energy possessed by a body because of its motionso…. a. making a meal: human body “making” = motion , a meal.. Kineticb. same.. moving vehicle, walking to school. however, if you just drank a pot of coffee and are sitting still on a bus you can have potential energy bc you arent currently using it but you have energy to spare. c. moving to a new apartment… you moving things would be kinetic. however, the charged battery of the moving trunk when its not running can be potential. d. playing in a rock band.. playing the drums in movement so kinetic. however, the charged amp can be a form of potential while its not in use

A. While cooking, the chemical energy stored in the natural gas used to warm the stove in converted to heat energy. Kinetic energy is the acts of cutting, stirring, putting things in the pot. The potential energy is in the form of the food you eat, which is stored in your body until the food is broken down, releasing the energy stored in the food.

B. Chemical energy is converted in your body by walking, or by the vehicle in which you’re travelling when the engine converts the chemical energy in gasoline to mechanical energy. The movement is kinetic energy. Potential energy comes from any changes in elevation you experience as you travel. The higher you are in relation to where you started, the more potential energy is present.

C. Once again, energy is converted by your muscles as you lift your belongings. The actual movement from place to place is kinetic energy, and there is potential energy as you lift things from the ground.

D. Playing music converts electrical energy into sound energy (if you have any electric amplification). Moving your arms or fingers represents kinetic energy. If you’re on a stage, you have potential energy because you can always step down to the lower level.

Photovoltaic | Please Help Me With Photovoltaic Systems?

what are two advantages of using it? and what are two disadvantages of using it?

Photovoltaic cells convert light energy falling on them in electrical voltage. Once electrical energy is available you can put it to different uses.Disadvantages are they are still costly and are not economical for large scale application.Most of them are used to harness solar energy and get electricity.So they can be used only when there is Sun light,Batteries can be charged when sun is shining and can be used latter.
