Solar panels are used for harnessing solar energy. This solar energy is then used to charge an electric cell and this electric cell is used to move a toy. What are the energy changes that take place?
solar energy- chemical energy- kinetic energy
Solar energy is converted in to electrical energy with the help of solar panels.
When the electric cell is charged, the electrical energy is converted and stored in the form of chemical energy.
This cell when connected to a toy, the chemical energy converts back to electrical energy and moves the toy resulting in kinetic energy.
