A. Electric Motor Bike

When you ride an electric motor bike, several energy transformations occur to enable the bike to move. These transformations are crucial for the bike's operation and are essential to understand the underlying physics.

1. Chemical Energy to Electrical Energy

The electric motor bike is powered by a battery, which stores chemical energy. When the battery is connected to the motor, the chemical energy is converted into electrical energy. This process is known as electrochemical reaction, where the battery's electrodes and electrolyte facilitate the conversion of chemical energy into electrical energy.

2. Electrical Energy to Mechanical Energy

The electrical energy from the battery is then transmitted to the motor, which converts it into mechanical energy. This is achieved through electromagnetic induction, where the motor's coils and magnets interact to produce a rotating magnetic field. The motor's shaft then converts this energy into rotational kinetic energy, propelling the bike forward.

3. Mechanical Energy to Thermal Energy

As the motor operates, some of the mechanical energy is converted into thermal energy due to friction and electrical resistance. This heat is dissipated through the motor's casing and is often released through the bike's exhaust system.

4. Kinetic Energy to Potential Energy

When the bike is in motion, its kinetic energy is converted into potential energy as it gains altitude or climbs a hill. This energy transformation is essential for the bike's operation, as it enables the bike to overcome obstacles and maintain its speed.

B. When Search is On an Electric Fan Starts to Rotate

When you turn on an electric fan, several energy transformations occur to enable the fan to rotate. These transformations are crucial for the fan's operation and are essential to understand the underlying physics.

1. Electrical Energy to Mechanical Energy

The electric fan is powered by a wall outlet, which supplies electrical energy to the fan's motor. The motor then converts this electrical energy into mechanical energy through electromagnetic induction, where the motor's coils and magnets interact to produce a rotating magnetic field.

2. Mechanical Energy to Rotational Kinetic Energy

The motor's shaft converts the mechanical energy into rotational kinetic energy, which is then transmitted to the fan's blades. The blades then convert this energy into a rotating motion, propelling the air forward.

3. Rotational Kinetic Energy to Thermal Energy

As the fan operates, some of the rotational kinetic energy is converted into thermal energy due to friction and electrical resistance. This heat is dissipated through the fan's casing and is often released through the fan's motor.

4. Potential Energy to Kinetic Energy

When the fan is turned on, its potential energy is converted into kinetic energy as it gains speed and starts to rotate. This energy transformation is essential for the fan's operation, as it enables the fan to move air and maintain its speed.
