One example of using chemical energy to produce kinetic energy is the process of burning fuel in an engine to generate motion. This is commonly seen in vehicles such as cars, motorcycles, and airplanes.

To understand why this activity is an example of using chemical energy to produce kinetic energy, let's break it down step by step:

1. Chemical Energy: Fuel, such as gasoline or diesel, contains stored chemical energy. This energy is released through a chemical reaction when the fuel combines with oxygen in the presence of heat or spark.

2. Combustion: When the fuel is ignited in an engine, it undergoes combustion, which is a rapid chemical reaction. The bonds between atoms in the fuel molecules are broken, and new bonds are formed with oxygen atoms from the air.

3. Expansion of Gases: During combustion, the fuel's energy is converted into thermal energy, raising the temperature and pressure of the gases produced. The high-pressure gases, including carbon dioxide and water vapor, rapidly expand.

4. Kinetic Energy: The expansion of gases creates a high-pressure environment inside the engine, which forces a piston to move. The linear motion of the piston is converted into rotational motion through a series of mechanical components, such as crankshafts and gears.

5. Output of Kinetic Energy: Finally, the rotational motion is transmitted to the wheels or propellers, resulting in the desired movement of the vehicle. This is the conversion of chemical energy into kinetic energy, which allows the vehicle to move.

In conclusion, the activity of burning fuel in an engine is an example of using chemical energy to produce kinetic energy, enabling vehicles to move and generate motion.
