Final answer:
The force of gravity and friction play a role in walking to school. Electrical energy from a bulb is converted to light energy when reading a textbook. A car converts chemical energy to mechanical energy when driven.
Step-by-step explanation:
Out of the given statements, the ones that accurately describe the conversion of energy in different scenarios are: The force of gravity and friction play a role in walking to school. When you walk, the chemical energy stored in your body is converted into mechanical energy to overcome the force of gravity and to propel you forward. Additionally, the friction between your shoes and the ground helps to convert some of the mechanical energy into heat energy. Electrical energy from a bulb is converted to light energy when reading a textbook. The electrical energy is converted into radiant energy (light) when it passes through the filament of the bulb, causing it to glow and emit light. This allows you to see and read the textbook. A car converts chemical energy to mechanical energy when driven. The chemical energy stored in gasoline is converted into mechanical energy when it is burned in the car's engine. This mechanical energy then propels the car forward. In each of these scenarios, there is a clear conversion of one form of energy into another, demonstrating the principle of energy transformation.
