For each of the following situations, identify the energy transformation that takes place:
a truck moving uphill
Kinetic energy to Potential energy
unwinding of a watch spring
Potential energy to Kinetic energy
photosynthesis in green leaves
Radiation energy to Potential energy
water flowing from a dam
Potential energy to Kinetic energy
burning of a matchstick
Potential energy to Heat and Radiation energy
explosion of a fire cracker
Potential energy to Kinetic energy, Heat, Sound, and Radiation energy
speaking into a microphone
Sound energy to Electrical energy
a glowing electric bulb
Electrical energy to Radiation and Heat energy
a solar panel
Radiation energy to Electrical energy
Explanation
The answers are derived by applying the definitions and examples of energy transfer provided in the text. The context defines kinetic energy as energy due to motion and potential energy as energy stored due to deformation or relative position. It also explicitly mentions that water in dams converts potential energy to kinetic energy. Other forms of energy transfer mentioned include heat, radiation (Sun's energy), sound waves, and electric circuits, which are used to deduce the transformations for photosynthesis, burning, microphones, bulbs, and solar panels.
