My knowledge about energy is very limited. I would like to find out other people's opinions about the phyical or non-physical attributes of energy.
Yes, energy is considered a physical entity because it has properties such as mass, volume, and can be measured and observed in the physical world.
Energy can exist in various forms, including kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), chemical energy, electrical energy, and nuclear energy.
According to the law of conservation of energy, energy cannot be created or destroyed, but it can be transformed from one form to another.
No, energy and power are not the same. Energy is the ability to do work, while power is the rate at which energy is transferred or transformed. In other words, power is the amount of energy used per unit of time.
Energy is typically measured in joules (J) or kilojoules (kJ), but it can also be measured in other units such as calories, kilowatt-hours (kWh), or British thermal units (BTU).
