A cellphone converts electrical energy from the battery into electromagnetic energy to send and receive signals to communicate with cell towers. Additionally, the screen and processor use electrical energy to display information and run apps.
A cellphone produces electromagnetic energy in the form of radiofrequency radiation to communicate with cell towers. This energy is used to transmit and receive signals for voice calls, texts, and data transfer.
A cellphone battery converts chemical energy into electrical energy. When the battery is connected to a device, the chemical reactions within the battery generate the flow of electrons that powers the device.
When a cellphone is turned on, electrical energy is used to power on the device and convert it into the various forms of energy required for its functioning: radio frequency (RF) energy for communication with cellular networks, light energy for the screen display, and thermal energy due to the device's internal components operating.
Bones do not directly utilize energy for movement. Muscles, which are attached to bones, require energy in the form of adenosine triphosphate (ATP) to contract and generate movement. The bones themselves do not use energy for movement.
