When starting a car, electrical energy from the battery is converted into mechanical energy. This electrical energy powers the starter motor, which then turns the engine's flywheel. As the engine starts running, it transitions chemical energy from the fuel into mechanical energy to power the vehicle. This process ultimately allows the car to operate and move.
A common example of conversion of chemical energy to mechanical energy is in a car engine where the combustion of fuel releases energy that is then converted into mechanical energy to move the vehicle.
When a man fills his car with gas, he expects a conversion of chemical energy into mechanical energy. The gasoline contains stored chemical energy, which is released during combustion in the engine. This combustion process converts the chemical energy into thermal energy, which is then transformed into mechanical energy to power the car's movement.
When a solar-powered car is moving, the energy conversion involved is solar energy being converted into electrical energy by solar panels, which is then stored in a battery. The electrical energy stored in the battery is then converted into mechanical energy by the motor to propel the car forward.

Three conversions in energy transformation may include chemical energy in gasoline converting to thermal energy in a car engine, then to mechanical energy to move the car, and finally to kinetic energy as the car moves.
Chemical (gas) to thermal (combustion) to mechanical More Simply: Chemical Energy to Mechanical Energy
chemical potential energy converting to kinetic energy
The sound energy produced from a car coming to a screeching halt is not a useful form of energy, as it represents energy lost in the conversion process. In this case, the kinetic energy of the car is being converted into both heat and sound energy, which are typically considered wasted energy.
In a car, energy conversion primarily occurs in the engine, where chemical energy stored in fuel (gasoline or diesel) is converted into mechanical energy. This mechanical energy drives the car's wheels, allowing it to move. Additionally, some energy is transformed into thermal energy due to friction and engine heat, which is often a loss rather than a useful output. In electric vehicles, electrical energy from batteries is converted into mechanical energy to power the wheels.
No because mechanical energy means that something is being physically moved.
Chemical Potential Energy to kinetic energu
When a car slows down, its kinetic energy decreases as it loses speed. This kinetic energy is converted into other forms of energy, such as heat generated by the brakes and friction between the tires and the road. Thus, energy is conserved through this conversion process.
