Chemical energy to mechanical energy.
Energy transformation has occurred.
Energy transformation has occurred.
A moving car transforms chemical energy from gasoline into kinetic energy of motion and heat energy through combustion in the engine. Additionally, some mechanical energy of the car's motion is transformed into thermal energy due to friction with the road and air resistance.
The movement of a car engine is considered physical, as it involves the transformation of mechanical energy into motion. Chemical reactions may occur within the engine, such as combustion in the cylinders, but the overall process is primarily physical in nature.
True
The chemical energy is transformed in kinetic energy.
Chemical Energy to Mechanical Energy
A moving car has kinetic energy, which is the energy of motion. This energy is determined by the car's mass and speed.
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.
Chemical energy to mechanical energy
In a battery-powered toy car, chemical energy stored in the battery is converted to electrical energy when the circuit is closed. The electrical energy powers the motor, where it is transformed into mechanical energy that drives the wheels of the toy car.
