Three examples of how energy transforms from one type to another?

Answer 1

Chemical Energy Transformations

Chemical <-> Light,

Chemical <-> Mechanical,

Chemical <-> Electrical,

Chemical <-> Heat.

Answer 2

-- Wind (moving air) (kinetic energy) ===> turns windmill ===> electrical energy

-- Gasoline (chemical energy) ===> makes car move (kinetic energy)

-- Battery charger (electrical energy) ===> charges battery (chemical energy)

-- Propane (chemical energy) ===> fuels barbecue (thermal energy)

-- Ribs from barbecue (food energy) ==> powers muscles ==> to run around the block (kinetic energy)

-- Battery (chemical energy) ==> used in flashlight (electrical energy) ==> lights bulb (light and heat energy)

Answer 3

1. When a ball is thrown, potential energy from the person's muscles is converted into kinetic energy of the moving ball.
2. Solar panels convert sunlight (light energy) into electrical energy.
3. Wind turbines transform wind energy into mechanical energy to generate electricity.

Answer 4

an old steam locomotive:

burn coal (chemical)

heat water to high pressure (potential energy)

move cylinders (mechanical energy)

to move the loco (kinetic energy).

Answer 5

Body heat, sunlight, and radio waves are three examples of energy.
