When a bulb lights up on passing current, the change of energy is
- from electrical energy to heat energy
- from electrical energy to light energy
- from electrical energy to heat and light energy
- from electrical energy to mechanical energy
The correct statement is
- Both work and energy have the same units
- Potential energy of a body is due to its motion
- Kinetic energy of a body is due to its position or state
- Kinetic energy can change into potential energy, but potential energy cannot change into kinetic energy
